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, hari-hly 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, 

 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 tianslucent white. 

 Mouth the entire length of the shell, being considerably produced 

 posteriorly, where 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^ 

 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.

This species, whose thin and famished look suggested the name 

 chosen, belongs to the group of which the Mediterranean Uh'icuhis 

 striatula (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 si)ecies of the Chal-
