CEPHALOPODA FEOM THE CALCUTTA MUSEU.AI. 19 



OCTOPODA. 



Family PTEEOTI. 



ClKRHOTEUTHIS PACIFICA, Hoyle ? 



A small and mutilated specimen, captured at a depth of 265 fathoms iu the Audamau 

 Sea, has been referred to this species. 



Family OCTOPODIDiE.* 



Octopus vuiiGABis, Lam. 



One large female from the Andamans, and one smaller male from Point Galle, Ceylon. 

 These specimens resemble very closely our common Octopod, and I could find no 

 important distinction between the European and Indian forms. 



Octopus granulatus, Lam. 



Eleven specimens have been placed in this species. Three come from Port Blair, three 

 from the Andamans, one from Great Cocos Island, one from Bombay, two from the 

 Southern portion of the Malacca Straits, and one from Maskat in Arabia. 



Octopus globosus, AppeUof. (PI. 5. fig. 81.) 



One specimen from the Nicobars, one from the Kabusa Islands (Mergui Archip.), five 

 from the Southern jiortion of the Malacca Straits, three from Bombay, and one from 

 Point Galle, Ceylon — in all eleven specimens have been referred to this species. The 

 extremity of the hectocotylized arm of a male is shown in figure 81. 



Octopus pictus (Brock), ^SbV.fasciata, Hoyle. (PI. 5. fig. 82.) 



One male specimen from Port Jackson, Avhich agrees very closely with the specimen 

 described by Hoyle in the 'Challenger' BejDort. The extremity of the hectocotylized 

 arm, however, shown in fig. 82, difiers considerably from that described by Hoyle in 

 Oct. maculosus (Proc. U. Phys. Soc. Edinb. vol. viii. 1883), w^hich he considers to be the 

 same species. It seems probable that the var. fasciata may have to be separated as a 

 distinct species. 



Octopus Januarii, Stp. 



Three specimens appear to belong to this widely distributed and abyssal species. One, 

 a female, comes from a depth of 193 fathoms in the Bay of Bengal (lat. 20° 17' 80" N., 

 long. 88° 30' E.) ; the othei- two are males captured at a depth of 271 fathoms in the 

 Andaman Sea. 



The ridges on the hectocotylized tip of the arm in the male are more marked than in 

 the figure given by Hoyle in the 'Challenger' Report (i), but in aU essential respects 

 these specimens agree with his description. 



* I must express my thanks to Mr. W. E. Hoyle for kiudly cxaminiug some of these Octopods.
