918 MR. F. E. BEDDARD ON ISOPODA COLLECTED [DeC. 1, 



The abdomen is long and narrow, about as long as the last three 

 segments of (he thornx ; it terminates in a short conical process. 



The antennae are very long, measuring about 3H millim. ; the fla- 

 gellnm is about as long as the peduncle, and is not distinctly jointed. 



The mandibles are conical in form, with only a single tooth-like 

 process ; they have no palp. 



The uropoda are short and uniramose, biarticulate. 



Station 147, 1600 fathoms. 



EuRYCopE, Sars. 

 Of the eight species described in the following pages, four have 

 been assigned to the genus Eurycnjje, chiefly as a matter of conve- 

 nience. E. novce-zealandia, E. fragilis, E. ntlantica, and E. iiiter- 

 media are, I am convinced, rightly assigned to this genus ; of the 

 other species, E. sarsii and E. spinosa are probably rightly placed, 

 while with regard to E. pellmida and E. abyssicola I do not feel 

 capable of pronouncing a decided ojnnion ; they may be the repre- 

 sentatives of a new genus altogether, but the specimens are so im- 

 perfect that I do not feel justified at the present moment in remov- 

 ing them from Eurycope, especially since there are no strong reasons 

 to be deduced from the organization of the species, which are 

 decidedly against such a view of their affinities. 



1. Eurycope kov-e-zealandi^e, n.sp. 



Of this sjiecies a large number of individuals were dredged off 

 the N. island of New Zealand. The largest examples measuie up 

 to 12 millim. in length. 



The head is smooth and narrower than the first segment of the 

 thorax ; the four first thoracic segments are excavated dorsally and 

 increase gradually in lateral diameter up to the fourth, which is the 

 widest ; the antero-posterior diameter of the first segment is con- 

 sideiably longer than the three succeeding segments, which are 

 subequal. In the median dorsal line of sejiments 2-4 (inclusive) is 

 an ujnight spiny process directed somewhat forwards. The lateral 

 mf.rgins of segments 3 and 4 are prolonged into a forwardly directed 

 spine ; two similar sjiines are found upon the epimera of these and 

 of the preceding segments. The three posterior segments of the 

 thorax are directed backwards ; they are closely adpressed and con- 

 vex dorsally ; on either side of the median dorsal line of each 

 segment is a ]iair of blunt tubercles which in other species {E. frayilis 

 and E. atlantica) are prolonged into spines ; the lateral n)argiiis of 

 these segments are directed forwards as spiny processes. The abdo- 

 minal segment is loughly triangular in form, terminatiiig in an 

 obtusely pointed extremity ; just in front of the articulation (pf the 

 nroj)oda is a short lateral process on either side ; the antero lateral 

 marjiins are prolonged into short, flattened, spiny processes corie- 

 sponding with those upon the thoracic segments. 



The antenrse are rather more than twice the length of the Iiody. 



The nropoda aie birainose and very minute ; the inner branch 

 shorter and more slender than the outer branch. 



Station l(i8, 1100 fathoms.
