and a very beautiful, large, undescribed species with large 

 kidney-shaped lumps on the body-wall, giving it somewhat the 

 appearance of a bunch of grapes, for which a new genus will 

 have to be established. 



The two lime-sponges, Leucosolenia clathrus and Leucoso- 

 lenia cerebrum, have been found here by Professor Kirk ; the 

 former occurs in the English Channel and the latter in the 

 Adriatic. 



Of cchinoderms, Amphiura elegans {A. squamata) is widely 

 spread in the North Atlantic ; Stichaster insignis is the southern 

 representative of the far northern form *S. albulus — the two 

 species are remarkably near, and both increase by subdivision ; 

 and Cribrella compacta is a near ally of C. occulata. The little 

 heart-shaped sea-urchin Echinocardium australe extends into the 

 North Pacific, but this has a great bathymetric range, having 

 been obtained from a depth of 2,675 fathoms off Japan. It is 

 very closely related to the Atlantic species E. cordatum. The 

 only genus of echinoderms peculiar to New Zealand is Ophiopteris, 

 with but one species, 0. antipodum. 



The large gephyrean worm Echiurus neozelanicus, which 

 occurs freely in Wellington harbour, is nearly allied to its con- 

 gener E. unicinctus of Japan. Priapulus caudatus, which occxirs 

 along the coasts of Greenland, Norway, and Great Britain, and 

 in both the North and Baltic SeaS, was found by the " Southern 

 Cross " Expedition in the Antarctic off Cape Adair. Mr. Shipley 

 says, " The genus, too, seems also bipolar in its distribution. 

 P. bicaudatus lives in the North Sea and Arctic Ocean, and is 

 represented in habits and its two tails by M. de Guerne's Piapu- 

 loides australis from the neighbourhood of the Magellan Straits " 

 (Rpt. " Southern Cross " Collections, p. 285). Mr. A. Willey, 

 in his report on the Polychseta of the " Southern Cross " Expedi- 

 tion, says, " Perhaps the most interesting feature of the collec- 

 tion is the addition of the characteristic northern maldanid, 

 Bhodine loveni, Magn., to the Antarctic fauna. Besides this, 

 two other genera not hitherto recorded in the south are re- 

 presented by species slightly different from their northern 

 congeners — namely Gatlyana (= Ngchia) cristata, n. sp., and 

 Malmgrenia crassicirris, n. sp. (p. 262). 



The stalked ascidian Boltenia pachydermatina, which is 

 abundant at low water on our southern coasts, in the colder 

 water of the Antarctic Drift, occurs also on the coasts of Green- 

 land. 



Eighteen species of New Zealand Bryozoa are identical or 

 closely related to European forms — namely, Scrupocellaria 

 scrupea, Bugula neritina, B. avicularia, Membranipora menibra- 

 nacea, M. pilosa, M. lineata, M. solidula, Microporella ciliata.
