TO INDIAN CAECINOLOGT. 453 



This is the commonest Stomatopod on the Soutli Indian coast. My largest specimen 

 is 147 mm. long. 



Distribution. From India to China, Japan, Australia, and the Pacitic generally, as far 

 as New Zealand and the coast of Chili.

Madras ; Sunderhunds {Brit. 31ms.) ; Rameswaram (J. R. II.). 



This species is closely allied to »S'. nepa, with which it has prohahly often been con- 

 fused, and the two are not separated by Miers in his Revision of the Squillidai ; the 

 distinguishing characters, though slight, appear however to ha constant. The two 

 species are sepai'ated by Dr. H. J. Hansen, who has i-ecently examined the Stomatopoda 

 in the British Museum. 



In *S'. affinis tlie eyes are mvich larger than in .S". nepa, with their corneal portions 

 greatly dilated and oblique ; the free thoracic and abdominal segments arc more strongly 

 carinated dorsally ; and very constantly the median line or sulcated carina of the carapace 

 widens anteriorly to enclose a very short oval space, situated behind the frontal plate, 

 whereas in specimens of S. nepa, of similar size, the space so enclosed is fully twice as 

 long, and extends almost half-way back between the frontal plate and the transverse 

 line which interrujits the median carina. 



Distribution. 3i\i)an{De JIaau) ; Chma (Dcrtholti, Brit. Miis.); Port Curtis, Australia 

 {Brit. IIus.) ; Ceylon {Seller). Probably some of the localities recorded for S. nepa 

 i-efer to the present species.

S. Scorpio (Latr.), Micrs, Ann. Mag. Nat. Hist. scr. 5, vol. v. p. 18, pi. ii. fig. 7 (1880). 



Madras, not uncommon {J. R. II.). 



The colour-markings are characteristic. Four almost confluent dark spots are arranged 

 transversely oit the dorsal surface of the second abdominal segment, a large spot is seen 

 on the proximal joint of the exopodite of the terminal abdominal appendages, and the 

 lateral process of the first free thoracic segment is also dark in colour. 



Distribution. From India to China and Australia.

Sunderhunds {Brit. JIus.) ; Madras {J. Ii. II.). 



A specimen from Madras in the Madras Central Museum measures thirteen inches in
