388 REPORT— 1880. 



Porcupine to the entrance of the Bay of Biscay, was found to be the most 

 abundant species within the bay, though in size greatly dwarfed as com- 

 pared with Norwegian specimens. A Thysanopoda, probably norvegica, 

 was taken several times abundantly, and was probably caught as the 

 dredge approached the surface. The large, most remarkable, and blood- 

 red Schizopod Gnatliopliausia Zoea, Willemoes-Sahm, which was dis- 

 covered in the Challenger Expedition near the Azores and off the coast of 

 Brazil, delighted us with its beauty. Many undescribed species were met 

 with. Pre-eminent among these were a new genus allied to Dromia ; ' a 

 very curious new genus of Galatlieidce, which is blind, and has the eye- 

 stalks converted into spine-tipped processes; a new PalcBViouid, remark- 

 able for having its carapace girt with a ring of spines ; and a Scalpellum, 

 apparently new. 



Among the Gephyrea were two species recently described by Danielssen 

 and Koren, from the Norwegian coast, and not hitherto found further 

 south ; the grand Sipunmdus priapidoides, which is the largest and most 

 interesting species of the genus known to me ; and the curious little 

 Ochnesoma Steenstrupii. This latter species I dredged last year in great 

 abundance at the mouth of the Hardanger Fiord, Norway. A third 

 Gephyrean obtained is also perhaps the Phascolosoma scpiamatum of the 

 same authors. 



In the Fosse de Cap Breton the curious Annelid, Siernaspis thalasse- 

 mo'ides, Otto, which was formerly refeiTed to the Gephyrea, was found 

 abundantly. 



Several examples of the much- disputed Ghcetoderma nitidulum were 

 obtained. This is one of those animals which, exhibiting relationship to 

 more than one class in almost equal ratio, becomes, by its somewhat inter- 

 mediate characters, of special interest. 



Only a single Polyzoon occurred. This was Triticella BoecMi, or an 

 allied species. It was infesting the crab Geryon iridens, on which same 

 host the species just named was discovered by Professor G. O. Sars. 



There was a remarkable absence of Hydrozoa. 



In no class is the collection finer than among the Actinozoa. Of 

 Actinians not secreting a corallum there were a new Pahjtlioa parisitic on 

 the spines of Cidaris papillata; an Actinia (^Adamsia?), parasitic on an 

 Isis ; and two or three other things which were not recognised by us. 

 Of corals there were Caryophyllia davits ; a Flahellum belonging to the 

 Flahelhim aperhim group, in which the corallum is little or not at all com- 

 pressed ; a Deltocyathus, and Lophohelia prolifera. Of Gorgonian allies 

 there were Gorgonia verrucosa, and at least two species of Isis, one of 

 which was of considerable size, and when dredged at night was gorgeously 

 phosphorescent, exhibiting a blaze of light. Of Virgularians there were 

 many fine species, including two large forms of Virgularia (or closely allied 

 genus) ; what appeared to be a Scytalium of very elegant form and bright 

 red, widely separated fins ; a genus which, from the curved, flaccid state 

 of the polyparium, appeared to be devoid of all calcareous axis ; Kopho- 

 ielemnon sfelliferum, and an example of the genus Umielhiria.^ This 

 genus, first discovered in the Arctic seas in 1753, and admirably figured 

 by old Ellis, was lost sight of for 120 years, when it was rediscovered by 

 Lindahl in the Swedish expedition between Greenland and Newfoundland. 



■ M. AlphoDse Milne- Edwards had previously seen this among the Crustacea 

 dredged by A. Agassiz in the Blalie, and proposes to name it Bioranodromia ovata, 

 • Probably U. Thomsoid, Kolliker.
