TO INDIAN CAKCINOLOGY. 345 



Genus Chlorinoides, Haswell. 



15. Chlorinoides aculeatus (Milne-Edwards). 



Chorinus aculeatus, Milne-Edwards, Hist. Nat. Crust, t. i. p. 316 (1834). 



Paramithrax {Chlorinoides) aculeatus, var. armatus, Miers, ' Alert ' Crust, p. 193, pi. xviii. fig. A 

 (1881). 



Gulf of Martaban, two males (Oates). 



Tlievar. armatus is distinguished, according to Miers, only by the form of the postocular 

 spine; but he has apparently overlooked De Haan's figure of Maja {Chorinus) aculeata, 

 M.-Edw. (Crust. Japon. tab. xxiii. tig. 2), in which the postocular spine is represented of 

 the same form as in this variety. Miers mentions the existence of spines at the distal 

 end of the meropodites of the ambulatory legs, which are also represented in De Haan's 

 figure, so perhaps the so-called var. armatus is really the typical form. 



The carapace of the larger specimen is 20 mm. long and 14 mm. broad, the rostral 

 spines 14 mm. long. 



Distribution. Japan, N. Australia. 



16. Chlorinoides Coppingeri, Haswell. 



Paramithrax Coppingeri, Haswell, Catal. Austral. Crust, p. 15 (1882). 



Chlorinoides coppingeri (Hasw.), Miers, 'Challenger ' Brachyura, p. 53, pi. vii. fig. 3 (1886). 



Muttuwartu Par {Thurston) ; Gulf of Martaban, two young specimens (Oates). 



These agree completely with dried specimens in the British Museum named by Miers, 

 except that the cardiac spines are scarcely united basally. They are probably not full- 

 grown, as the carapace of the largest measures only 12 mm. long. According to Miers 

 it is perhaps a variety of C. longispinus, De Haan. 



Distribution. N.E., N., and W. Australia (Haswell, Miers); Bass Strait (Miers). 



Genus Naxia, Milne-Edwards. 



17. Naxia hirta (A. Milne-Edwards). 



Naxioides hirta, A. Milne-Edwards, Ann. Soc. Entom. France, ser. 4, t. v. p. 143, pi. iv. fig. 1 (1865). 

 Podopisa Petersii, Hilgendorf, Monatsb. Acad. Wissensch. Berlin, Nov. 1878, p. 785, taf. 1. fig. 1-5. 

 Naxia {Naxioides) Petersii (Hilg.), Miers, ' Alert ' Crust, p. 523 (1884) ; De Man, Mergui Crust, 

 p. 19 (1887). 



Tuticorin, a female with ova ( Thurston). 



This specimen has more numerous tubercles on the carapace than are represented in 

 Hilgendorf's figure (a male), and the spine on the posterior margin of the carapace is less 

 acute ; the last feature is also noticed by De Man, owing probably to the fact that his 

 specimen, like the one which I have examined, was a female. The rostral spines are 

 entire in the Tuticorin specimen and measure only about 6 mm. in length, while the 

 carapace (including rostral spines) measures 31 mm. in length. 



Distribution. East Africa, Amirante Is., Andaman Is., Philippines.
