almost lamellar — with sharp edges, the inner of which is finely crenu- 

 late ; in the adult male its length is nearly three times its breadth. The 

 fingers, which are not as long as the hand, are also very thin and lamel- 

 lar, and are elegantly curved : their opposed edges are sharp and entire, 

 the cutting edge of the immobile finger being rather thickly fringed 

 with hair. 



The legs are slender and smooth, except for a line of tiny granules 

 along the under surface of the meropodites. 



The abdomen of the male consists of a single linear and concealed 

 basal piece and a small triangular terminal piece, and, between the two, 

 a long smooth triangular piece, which is bilobed and granular at base 

 and has the sixth tergum demarcated by a deep groove. 



The colour in spirit is uniform coppery. 



The carapace of the adult male is 13 or 14 millims. in either 

 diameter, that of the female 12 or 13. 



In the Indian Museum collection are 40 specimens, adults and 

 young of both sexes, from the Andamans, Mergui, Karachi, and the 

 Persian Gulf. 



The Persian Gulf specimens, which are quite adult, have the dorsal surface 

 much mottled with green and brown, and the immobile finger denticulate beyond 

 the line of hair.

Philyra globosa, de Man, Journ. Linn. Soc, Zool., Vol. XXII. 1888, p. 202 : only 

 that part referring to Fabricius' female type and to the Mergui specimens. This re- 

 ference is placed first because Dr. de Man has examined Fabricius' types, male and 

 female, of P. globosa, and the species here under consideration corresponds with 

 Fabricius' female type as re-described by de Man.

The whole exoskeleton (when not incrusted with Mydrozoa, &c. t 

 as it commonly is) has, to the naked eye, the appearance of glazed porce- 

 lain, although when examined with a lens it is minutely punctulate and 

 gr anular.
