R. FAMELICUS Watson. PI. 21, fig. 6. 



Shell long, narrow, subconically cylindrical, with straight out- 

 lines, abruptly truncate above, with a deeply impressed papillary 

 apex, rounded and slightly tumid in front, harshly striate above 

 and delicately so below. Sculpture : Longitudinals the lines of 

 growth are very slight, but round the top of the shell is a coronal of 

 folds forming ridges and furrows of about equal strength ; these ex- 

 tend over the top and into the hollow crown. Spirals round the 

 top, harshly scoring the coronal, are four or five deep, but not broad r 

 sharp cut furrows, parted by flat surfaces of about twice their 

 breadth ; below these to a fourth of the length, there are distant 

 furrows so obsolete as to be almost invisible ; below this the whole 

 surface is superficially scratched with delicate sharp-cut fretted fur- 

 rows parted by broadish flat intervals. Color translucent white* 

 Mouth the entire length of the shell, being considerably produced 

 posteriorly, wkere it is slightly enlarged ; in the middle it is nar- 

 row, the two sides being almost perfectly parallel, in front it is elon- 

 gately oval ; in its entire shape it resembles a spoon. Whorls 4 t 

 but the earlier ones are so deeply sunken, and the hole in the 

 crown (where alone they are visible) is so small, that it is difficult 

 to count them ; the apex is papillary. Suture slight. Outer lip 

 rises straight from the crown, with a slight inclination in towards 

 the center, is narrowly rounded above, and advances straight for 

 about two-thirds of the shell's length, at which point it is slightly 

 expanded and then becomes somewhat patulous ; it sweeps rather 

 freely round to join the pillar. Top small, oblique, harshly radia- 

 tingly striate and deeply narrowly impressed. Inner lip long and 

 straight, slightly convex in front, oblique and slightly concave on 

 the pillar which is bluntly toothed in front, and has a very narrow 

 scarce patulous prominent edge with a minute furrow behind it. 

 Alt. 0*18 in., diam. 0'06. Mouth breadth at same place, 0019

This species, whose thin and famished look suggested the name 

 chosen, belongs to the group of which the Mediterranean Utriculus 

 striatala (Forbes) may be taken as a type, though in that species 

 the features attributed to the subgenus Sao (of Cylichna) are much 

 more strongly developed. Compared to this species of the Chal-
