I I:.' "TERRA NOVA" EXPEDITION. 



( Vphalopods were only once present, in shallow water on a, shelly bottom, 

 when four .specimens of the very local Polypus aunti'iilix (Hoyle) occurred. Other 

 species taken in plankton-nets in this region included Argonauta /V/7,/,r/', Maltzun, 

 which, as far as our knowledge goes, is absent from the Atlantic and Arctic 

 regions, and ranges in Polynesian and Indian seas from China and Hawaii to Australia 

 and New Zealand; Tinnor.topus riolitrcnx, Delle Chiaje, a cosmopolitan pelagic species 

 recorded from all seas except the neighbourhood of the poles, the most northerly 

 locality known being apparently Japan, and the most southerly the new records of the 

 "Terra Nova" ; larvae of Pyroteuthis (Pterygioteuthis) t/iardi, Fischer, a species with 

 a wide range in the Atlantic, Pacific and Indian oceans ; Rhynchoteutliion, of a type 

 recorded by ( 'him from the Indian and Atlantic oceans; Pyrgopsis pacificus (Issel), 

 a species widely distributed in the Pacific, having been recorded from Japan to Tahiti ; 

 and Teuthowenia antarctica, Chun, the type of which was taken at 55 57' S., 1G 14' E. 

 This species is very nearly allied to Ti'tit/mirt'iiid megalops (Prosch), a species of the 

 North Atlantic which has been found at various points from Greenland to the south 

 of the Canaries. A specimen of Monih'iitlii* ing ens, E. A. Smith, was taken at the 

 surface off Three Kings Islands. Pfeffer ('12, p. 112) enumerates thirteen Patagoriian 

 examples of this species preserved in various museums. Hoyle ('12, p. 28 1-282, fig. 1)) 

 records an example from the South Orkneys, and fragments of another, which were 

 taken in the stomach of a Ross' Seal from oft' the same island group. The only other 

 specimen known seems to be that brought to Cambridge by Darwin from the voyage 

 of the " Beagle." As regards the Atlantic specimens, quite a striking group was trawled 

 in forty fathoms on sandy ground at Station 41, off Rio de Janeiro, close to the Tropic 

 of Capricorn. This group included the only Myopsid, Semirossia ienera (Verrill), a 

 species limited to the Atlantic, where it has been recorded from Spitsbergen to the 

 south and west coasts of Patagonia ; Polypus ru<josux (Bosc) d'Orb., a species of the 

 South Atlantic, Indo-Malayan, Japanese and Australian regions ; Poli/pus hntcei, Hoyle, 

 the type male of which was taken oft' Tierra del Fuego ; and Mosrhites lirevis (Hoyle), 

 the type of which occurred a little south of this, off Monte Video. 



M<ix/'/i/t/'s turijueti (Joubiu) and Mowkitcs clutrcoti (Joubin) both extend their 

 range from within the Antarctic Circle, and from the South Shetlands and South Orkneys 

 to this point. Although the Rio de Janeiro specimen of M. i-lxuroti appears to be 

 exactly like the Antarctic examples, its locality suggests the possibility that the present 

 species, in spite of the various differences pointed out by Joubin ('05, p. 7), may after 

 all be only a form of Afowliitrs vi'rnicona (Verrill), a species of the north-east coast of 

 America. Joubin (op. cif., p. 17) remarks of M. rernii-osa and M. charcoti, " Ce sont 

 deux especes evidemment voisiues 1'uue de 1'antre." Polypus oninli'iitnlix (Steenstrup 

 MS.) was taken between tide-marks on the shore of South Trinidad Island, and has 

 been recorded previously from Ascension and the Galapagos Islands, as well as from 

 i lie type-locality of Cuba. A specimen of the cosmopolitan Onychoteuthis hunks! 

 (1 .each) was washed on boa I'd the "Terra Nova" south of Madeira, and the broad-
