260 Messrs. J. Wood-Mason and A. Alcock on 



notches in the posterior angles of the thorax and by the base 

 of the abdomen, whereby in all probability a current of fresh 

 water is caused to flow over the eggs. The rostrum is trian- 

 gular and shaped like the beak of a bird, and the antennary 

 flagella are visible from above beyond its margins. The 

 eyes, which are very small, are retractile against the sides of 

 the carapace, and the narrow orbital eave is provided with a 

 minute spine anteriorly and posteriorly. The legs are long 

 and slender, with their segments, including even the tapering 

 dactylopodites, cylindrical. 



Numerous specimens were obtained at Stations 81 and 96, 

 and at Station 76 over two hundred were taken, almost all of 

 them being males. This form, in fact, is characteristic of the 

 infra-littoral of the Bay of Bengal, near the 100-fathom limit, 

 from the coast of Arrakan to the Godavari.

 ambulatory legs pink.

Anamathia, S. I. Smith. 

 38. Anamathia Livermorii, sp. n., Wood-Mason. 



Closely allied to Anamathia pulchra, Miers, differing in 

 having the carpopodite and propodite of the chelipeds rounded 

 instead of carinate. 



The spines of the rostrum are as long as the distance in a 

 straight line from the hinder margin of the carapace to the 

 gastric spine. The carapace bears twenty spines disposed in 

 five longitudinal rows, namely two lateral of three spines each, 

 one dorsal of four, and two subdorsal of five each including 

 the postoculars. 



A male and two females from Station 56, 240 to 220
