Shell large, thick, bullet shaped with a silky appearance. Holotype: 41.5 mm in length. 14.6 mm in width. The protoconches are all broken oft, but in the holotype which is also dead taken but very fresh, the remains of the protoconch have the same color as the shell. There are 8 teleoconch whorls, the last whorl being very large, covering about 2/3 of the shell length. The aperture is large, about half the shell length or bigger. The shape of the body whorl is elongate-globose, a little concave where it changes into the broad siphonal canal. The suture is invisible: on the first whorls it is hidden into a deep subsutural channel, and this channel is closed by the following whorls in the last three teleoconch whorls. The sculpture is beautiful: it starts on the first teleoconch whorls with strong axial and spiral ribs that form a reticulate pattern. As the shell grows, the axial ribs become weaker and change into line striae. The spiral ribs become wider and give place to deep spiral grooves. There are 4 such spiral grooves between the top of the aperture and the suture of the last whorl. The aperture is oblique, narrow with a thick outer lip. The columellar area is covered with a glaze down to the tip of the siphonal canal. There are 5 not so strong columellar folds, the last one, near the siphonal canal, hardly visible. A small fasciole is present. The siphonal canal is wide. The color in dead shells is cream white with some dark and pale spots near the suture. The color in the fresh holotype is warm brown, paler towards the aperture with a pale band in the center. Where the suture is supposed to be. the shell develops pure white flecks. fading as they go down on the whorl. The aperture is pale brown inside and the glaze on the columella is transluscent in the upper part of the aperture, but whitish towards the siphonal canal.

This species belongs to the beautiful group of usually well sized solid Scabricola with a large aperture. Early specimens were confused and labeled as S. guttata (Swainson, 1824), an east African species. S. guttata is much more fusiform with straight whorls, while the whorls in S. geigeri n. sp. are much more convex. Adult specimens of S. geigeri are also larger. S. geigeri n. sp. is soft brown with a pattern of white spots below the suture and a pale band mid-whorl. S. guttata is more reddish brown and is usually covered with white spots, dispersed all over the shell. Spiral ridges on the body whorl in a classic S. guttata number 18. in the holotype of S. geigeri only 15. Another Scabricola closely related and living in the same area is S. petiti Poppe & Tagaro, 2006. This species is much smaller, has a broader outline and a typical pattern of dark spots set in dotted spiral lines below the shoulder. This feature is absent in S. geigeri n. sp. Also from the same area and of similar size, even bigger, is S. hayashii (Kira, 1959). This species has also straighter whorls, is heavier, has about 22 spiral ridges on the ventral side, dark flecks below the suture instead of white flecks and the shape of the lower body whorl is not concave, but convex.
Another species that resembles S. geigeri n. sp. at first glance is the M. prosphora Iredale, 1929 of which the holotype has been figured by Cernohorsky (1976). Most M. solida Reeve, 1844 as shown in literature are M. prosphora. The M. solida is the shell as shown by Robin & Martin (2004). M. prosphora differs from S. geigeri n. sp. by the smaller size of the spire, the shorter aperture with a convex shape where it touches the suture. The siphonal canal is not so wide and the coloration of white flecks is not too developed on the body whorl as it is in fresh specimens of M. prosphora.

TYPE LOCALITY
The Philippines. Aliguay Island.
DISTRIBUTION AND HABITAT
Central Philippines. Shells are dredged in Aliguay Island between 50 and 150 m deep on gravel bottoms. The paratype 4 was eollected in Panglao Island, a little to the north of Aliguay Island - southern Bohol, on a Xenophora at 360 m.
