strong spiral sculpture which characterises it, coupled with the

Doris tuberculata, Cuv. — This species is recorded in the “ Report 
of the Antarctic Expedition ” (E. A. Smith, Phil . Trans., vol. 
168, p. 183). “A Hudibranch brought from Kerguelen Island 
by the Antarctic Expedition has been identified as a variety of 
this common European species by Mr P. S. Abraham, who has 
recently been studying the species of this genus in the national 
collection. He says that it possesses no characters of specific dis- 
tinction from D. tuberculata , and differs from it only in a few 
slight and unimportant particulars attributable to mere variation.” 
Murray {Trans. Roy. Soc. Edin ., vol. xxxviii. p. 448) notes 
that Studer doubtfully records D. tuberculata from Kerguelen, but 
P»ergli considers the form referred to as probably identical with 
his Archidoris kerguelensis, and distinct from the northern form. 
I do not know that any conchologist has ascribed import- 
ance to these few and somewhat doubtful instances of identity 
between northern and southern shells. Mr E. A. Smith, in 
reporting on the Mollusca of Kerguelen, while calling attention to 
the apparent similarity of certain species to northern forms, dwells 
upon the great resemblance of the fauna as at present known to 
that of the Falkland Islands and South Patagonia ; while the Rev. 
A. H. Cooke {Cambr. Nat. Hist., “Mollusca,” p. 367) states that 
“ the Mollusca of Kerguelen Island and the Marion and Crozets 
groups show relationship partly with South America, partly with 
the Cape, and partly with South Australia and Hew Zealand, 
thus showing some trace of a circumpolar antarctic fauna corre- 
sponding to, but not nearly so well marked as, that of the circum- 
polar arctic sub region.” 
Kinetoskias cyatlius, "Wy. Th. — Recorded in the Challenger 
Report from 1525 fathoms off the coast of Portugal, and also from 
2650 fathoms, lat. 36° 44' S., long. 46° 16' W. This very remark- 
able Polyzoan is supposed by Koren and Danielssen to be identical 
with their K. Smittii from the north of Horway. Another species, 
K. pocillum, Busk, from near Pernambuco, lat. 9° 5' S., long. 
34° 49' W., and from 2160 fathoms off Valparaiso, is in like 
manner similar to Koren and Danielssen’s K. arbor escens from 
K or way.
