252 A. Alcock — Carcinological Fauna of India. [No. 2, 



tally forwards as a median tooth. Posteriorly a faint carina runs 

 straight backwards from the front, separating the hepatic regions, much 

 as in P. tridentata. 



3. The tooth on the third thoracic sternum, on either side of 

 the abdomen, though more outstanding, is much shorter, projecting 

 forwards only about halfway across the second sternum. 



4. The chelipeds of the adult male are not more massive than 

 usual, the arms being only about a quarter as broad as long, and 

 the hands being more than half again as long as broad. 



5. The fingers in the adult male, as in the female, are almost 

 smooth, and there is no big tooth near the middle of the mobile finger. 



6. There is but the faintest trace of a denticle on the male abdomen, 

 in the middle line. 



7. The colours are altogether different, even in a specimen that 

 has been over 20 years in spirit in the same bottle with specimens of 

 P. wood-tnasoni. 



In good spirit specimens the dorsal surface is light grey with 

 elegantly speckled markings of various shades of greenish and yellowish 

 brown, as follows : — a band across the tip of the front : a V-shaped 

 collar at base of front : a crescent on either branchial region, joining a 

 stripe down the middle of the postgastric and cardiac regions, the whole 

 looking like a scorpion with extended chelae : a broad band across 

 middle of arm and a narrow band across distal end of arm : a broad 

 band across middle of hand, and a narrow stripe along both fingers. 

 The ventral surface of the external maxillipeds and the tip of the 

 abdomen closely speckled and mottled with dark brown. 



Locality — Andamans, whence the Indian Museum collection has 3 

 adult males. 



The foregoing three species have more the general facies of 

 Leucosia than of Philyra. 



78. Pseudophilyra hlanfordi, n. sp. Plate VI. fig. 7. 



Carapace circular, its dorsal surface defined all round behind the 

 eyes by a'finely beaded line ; its regions are tumid and well demarcated, 

 the tumid surfaces being very distinctly granular (excepting the front 

 part of the gastric region) in the male, but in the female more punctate 

 than granular. The front is distinctly pinched off at base from the 

 hepatic regions, as in all the species of Leucosia except L. truncata, and 

 as in all other species of Pseudophilyra : it is divided into two rather 

 tumid lobes by a longitudinal groove that extends almost to its base: its 

 anterior edge is straight, and projects just beyond the edge of the 

 epistome.
