CARCINOLOGICAL STUDIES. 59 



I consider this species to be identical with Calcinus 

 latens (Rand.) Dana, finding no difference of any impor- 

 tance between the original specimen of intermedius from 

 Djeddah , Red Sea, and a specimen from Tahiti, which 

 I formerly referred to Dana's species. The granules with 

 which the fingers of the larger hand are covered , are more 

 flattened and less prominent than in the Tahiti specimen, 

 but this may perhaps be ascribed to the larger size of 

 the Red Sea specimen, in which the granules are more 

 worn of. This species may be distinguished both from 

 Calc. elegans M. E. and Calc. nitidus ^e\\. by the quite 

 different coloration, as well as by the lower mar- 

 gin of the left hand being sharp and granulate, and 

 by the dactylopodites of the second and third pair of legs 

 being more slender and almost as long, but not shorter 

 than the propodites. The fingers of the larger hand are 

 also but finely granulate and they are not provided with 

 the larger tubercles which are characteristic of Calc. elegans. 



This species may at first sight be recognized by the 

 dark violet coloration of the basal half of the dactylopo- 

 dites of the second and third pair of legs ; these legs are 

 clothed with some tufts of hair especially on the last joints. 



Calcinus latens has been recorded by Richters from 

 Mauritius, and by Dana from the Indian Archipelago, the 

 Fiji- and the Sandwich Islands.

The Leyden Museum received two specimens of this 

 Atlantic species from the Samoa Islands. 



Prof. Milne Edwards enabled me to compare them with 

 a type-specimen of Brulle's Squilla oculata from the Cape 

 Verd Islands, and I cannot find differences of any im- 

 Ndtes from tlie Leyden ]MuseuEu, Vol. X!III.
