207 Dominican Fossils — Maury 43 



Shell elongate, nearly or quite smooth, sometimes with a few 

 wavy spirals anteriorly, spire acute, rather low, with the later 

 whorls deeply channeled. Length 41, width 20 mm. Apparently 

 this is Gabb's unfigured species. 



One of our specimens from Cercado retains its delicate lin- 

 ear, revolving color pattern, of gray lines on a white background. 

 The color scheme is of the general style of C. lignarius Reeve.

Conus Olssoni, n. sp. 

 Plate 7, Figure 3 



Shell of medium size, very elongate, the length considerably 

 more than twice the width; spire one-twelfth of the total length. 

 Whorls eleven, the first two forming the protoconch rise abrupt - 

 ably above the following whorls, on which they rest like a min- 

 ute but striking pinnacle visible to the unaided eye. The three 

 whorls following the protoconch are flattened and discoidal, the 

 subsequent six slope more rapidly towards the shoulder angle of 

 the body whorl, they are convexly rounded between the deeply 

 impressed suture lines, and marked with slightly arcuate, oblique 

 growth-lines. The specimen described shows only very faint, 

 nearly obsolete striae on the spire. Body whorl roundly angu- 

 lated at the shoulder, thence tapering evenly and gradually to 

 the base, smooth except for a few irregular, more or less obsolete 

 basal striae. Length 38, width 16 mm. 



This species is named in honor of Mr. Axel Olsson, by whom 

 it was collected.
