specimens is without teeth in the emargination, a character not ob- 

 served in other species of the genus. 



RHINOCRICUS LEUCOSTIGMA Pocock 



Rhinocricus Icucostigma Pocock, Journ. Linn. Soc. London, vol. 24, pp. 500- 

 501, 1894. 



This species was found to be common in the vicinity of Roseau, 

 Dominica, in January 1932, but with a range of size less than that 

 credited to the species ; the largest specimen was 45 mm long and many 

 were less than 30 mm in length. 



Chamberlin' incorrectly assigned this species to the island of St. 

 Lucia instead of Dominica. 



RHINOCRICUS MARTINIQUENSIS Chamberlin 



Rhinocricus martmiquetisis Chamberlin, Bull. Mus. Comp. Zool., vol. 62, p. 199, 

 1918. 



Five specimens were found beside the road from Fort-de-France 

 to St. Pierre, Martinique, March 10, 1932. 



Although none of these specimens exceeds 30 mm in length, they 

 agree with Chamberlin's description in other particulars. His as-

sumption of the difference between the anal segment in this species 

 and R. leucostigma is correct, as was shown by direct comparison of 

 specimens. R. martiniquensis has the margins of the anal valves much 

 less compressed, and the median plate of the gonopods has the tip 

 longer, more slender, and the apex rounded. In R. leucostigma the 

 apex is almost squarely truncate.
