which successively increase in length from proximal to distal 

 and which interfit into the apertures of the opposed face of the 

 dactyl. 



As stated by Mr. Kemp, the secondary sexual characters are 

 strongly marked in this species. The adult males have the distal 

 end of the retrochela-propodus much wider than that of the 

 female; the proximal end of the related dactylus is also dilated 

 with the teeth shorter and the outer margin much more convex. 

 The adult males have the median carina of the telson much more 

 inflated and also the greater part of the distal margin is swollen.

Discussion: Through an unfortunate oversight which was 

 immediately corrected in the Errata (1930), Raninoides loevis 

 Latreille was cited in Volume II, Bulletin of the Vanderbilt Ma- 

 rine Museum, p. 48, as R. loevis lamarcki. The Perlas Islands 

 material above described, together with material from the Mar- 

 quesas Keys, Florida, has recently been separated from the latter, 

 without examination of the series of specimens, by Miss M. J. 

 Rathbun, who designates it as R. benedicti. The exceedingly trivial 

 characters which she ascribes as definitive of benedicti would 

 be of questionable value for specific rank, if they were based on 

 anatomic evidence and of constant status, which they are not. 

 These so-called "characters" are highly variable, within all series
