/ 18 ■ A. Alcock — Carcinological Fatina of India. [No, 1, 



Posterior border nearly straight, making a dentiform angle of 

 junction with the postero-lateral borders. 



Orbits deep, without any particular dorsal inclination, their major 

 diameter nearly equal to the width of the front ; the inner angle of the 

 lower border bilobed, the inner lobe dentiform and projecting beyond 

 the level of the tips of the frontal teeth. 



Merus of external maxillipeds produced a good deal beyond the 

 articulation of the flagellum. 



Chelipeds moderately massive, their length not If times that of the 

 carapace : a spinule at the far end of the anterior border of the ischium : 

 a spine near the middle of the anterior border, and a spinule near the 

 far end of the posterior border, of the arm : the inner angle of the wrist 

 is produced to form a spine nearly half as long as the palm, and on the 

 outer surface of the wrist are 3 spinules of which one is almost a spine : 

 hand not inflated, its upper surface with 2 costae and 3 spines of which 

 the one at the far end of the inner border is the largest ; a faint ridge 

 along the outer surface of the hand, and one or two along the inner 

 surface : fingers stout, nearly as long as the hand. 



First 3 pair of legs long and slender, the first pair well over twice 

 the length of the carapace. The fourth pair are very little shorter than 

 the chelipeds and have the merus slender and quite unarmed. 



2nd and 3rd abdominal terga strongly carinated in both sexes : the 

 6th tergum of the adult male is nearly as long as broad and has nearly 

 parallel sides. 



Colours in life salmon-pink above, tips of spines red. 



In the Indian Museum are 54 specimens from off the Malabar coast 

 56-68 fms., off the Coromandel coast 33 fms., and from the Andamans. 



The carapace of the largest specimen is 12 millim. long and 17 

 millim. broad.
