Closely allied to R. carinata A. Ads. (Proc. Zool. Soc. Lond. 185 1, p. 226) but more 

 coarsely sculptured, the number of radiating ribs being only about 34 and a few intermediate 

 ones; Adams says: "ornamented with very many simple, close radiating riblets; interstices 

 cancellated"; in the species now under consideration; the ribs are not simple but conspicuously 

 crenulated, the concentric lirae crossing the ribs.

According to the figures and collected specimens, this species seems to be rather variable 

 in colour; the specimen from Stat. 296 is nearly entirely yellowish-white, with a few rays and 

 spots, those from the other localities are much darker; however they agree sufficiently in 

 sculpture, to consider them as one and the same species.

Stat. 213. Saleyer. Reef, i Spec. 



Shell elongated-oval, obtuse in front, slightly depressed. Front slope very convex, side 

 slopes and posterior one less so, the latter concave just below the slightly eroded apex, which 

 is placed at about 73 of the total length. Colour white, with a few black spots on some of the 

 ribs, but no more than 3 on one rib; one of these spotted ribs on the front slope and 3 or 4 

 on each side. Sculpture consisting of 1 5 strong radiating ribs, with a thinner rib in each interstice, 

 and often with still fainter ones in the intervals; they are crossed by about 10 conspicuous, 

 concentric lirae, making the ribs crenulated, and numerous striae. Slit-fasciole shallow, with 

 numerous curved lamellae. Margin crenulated, angular in front, length of slit 17,; Mill, with 

 thickened margins and a short, flat rib towards the apex. Interior smooth, white, space within 

 the muscle-scar yellowish-brown, the ribs and black spots are visible through the shell.

I know no species' to which this is allied. E. punctata^ which agrees perhaps' in some 

 respects, is much more rounded. The small black spots give a very peculiar aspect to this species.
