Carcinological Fauna of India. 245 



Besides these there are 4 specimens (two males more than half-grown a 

 younger male, and one very yonng specimen) from Mergni. These have been com- 

 pared by Dr. de Man with Fabricius' types of P. glohosa from the Kiel Museum, and 

 are stated by him to agree with Fabricius' female type. 



They do not however, as Dr. de Man appears to suspect, agree with Fabricius' 

 male type, and this involves a delicate question of synonymy. 



From Dr. de Man's description it is evident that Fabricius' male is a speciea 

 quite distinct from his female : as a matter of fact it appears to be the species 

 named by Milne Edwards— and named probably with foresight— P. globulosa. 



It seems therefore preferable to apply Milne Edwards name, P. globulosa, to 

 Fabricius' male type, and to leave the name P. globosa in possession of Fabricius' 

 female type. 



The only other alternative is to make use of Dr. Henderson's name P. polita for 

 Fabricius' female, and to let P. globosa stand for Fabricius' male. But this, I think 

 would be a little unjust to Dr. de Man, upon whose prior work the present attempt 

 to clear up the confusion between the two species is based, and a little wanting in 

 respect to the memory of the founder of modern carcinology.

The whole exoskeleton (when not incrusted with Hydrozoa &c. 

 as it rarely is) has the somewhat greasy look and feel of uno-lazed 

 porcelain, except the legs and abdomen, which are polished. 



The carapace is circular, its dorsum is defined all round, behind the 

 hairy front, by a line of granules, some of which, at fairly regular in- 

 tervals, are much enlarged and may even, in young specimens, form 

 distinct denticles. 



The epistome can be scarcely said to project beyond the front, 

 since only the inner angles of the afferent branchial canals do so. 



The edge of the front is emargiuate in the middle line, so as to 

 make the front, when denuded of hair, broadly bilobed. 



An indentation of the margin of the carapace separates the hepatic 

 from the branchial regions, and a broad groove separates the branchial 

 regions from the cardiac and intestinal regions, on either side. 



A band of grauules visible to the naked eye is always found
