TO INDIAN CARCINOLOGY. 351 



The largest specimen (a female) has the carapace 8 mm. long and 7'5 mm. broad. In 

 this small species there is a well-marked channel on each pterygostomial area leading to 

 the branchial opening. The L. pisoides, Adams & White, is a closely allied species, and 

 the two are perhaps not distinct. 



Distribution. New Caledonia [A. Milne-Edwards); "Eastern Seas," and Fiji {Brit. 

 Mm.). 



32. Lambrus hopeonotus, Adams & White. 



L. hoplonotus, Adams & White, ' Samarang' Crust., p. 35, pi. vii. fig. 3 (1848). 



Muttuwartu Par, a male {Thurston). 



The single specimen belongs to the var. planifrons of Miers (Ann. Mag. Nat. Hist, 

 ser. 5, vol. iv. p. 24, pi. v. fig. 7) founded on specimens collected by Holdsworth in 

 Ceylon. The carapace is 12 mm. long, and 17*5 mm. in breadth including the lateral 

 epibranchial spines. 



Distribution. Ceylon, Malay Archipelago, N.E. Australia, New Caledonia. 



Genus Cryptopodia, Milne-Edwards.

 species. 



Distribution. N., N.E., and E. Australia, Malay Archipelago, Singapore, China, Japan.

Tuticorin, two females (one with ova) and a male {Thurston). 



These specimens completely agree as regards colour-markings with the original 

 description and figure of this very beautiful species ; the markings are doubtless protective. 

 The single male has the carapace flatter and slightly narroAver than in the females, and 

 in the former the propodus of the right chelipede is more strongly developed than that of 

 the other side. The largest specimen (a female with ova) has the carapace 11 mm. long, 

 and 105 mm. broad between the apices of the lateral spines ; the male is 9 mm. long 

 and 8 mm. broad. Z. lowjispina, Haswell, from Torres Strait, is distinguished only by 

 its longer and more acute spines, and is perhaps merely a local variety. 



Distribution. Sooloo Sea and coast of Borneo. C>-12 fathoms {Adams Sf White).
