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



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

 segments of the thor.ix ; it terminates in a short conical process. 



The antennae are verv long, measuring about 3fJ 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 14", 1600 fathoms. 



EuRYCOPE, Sars. 

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

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

 nience. E. norce-zealandia, E. fragilis, E. ntlantica, and E. inter- 

 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. yellvcida and E. abyssicola I do not feel 

 capable of pronouncing a decided opmion ; they m,ay be the repie- 

 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 nov^-zealandi^, n. sp. 



Of this species a large number of individuals were dredged off 

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

 to 12 niiliim. in length. 



The head is smooth and nr.rrower 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; tlie 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 sej;ments 2-4 (inclusive) is 

 an upright sjiinv process directed someuhat forwards. The lateml 

 mr.rgins of segments 3 and 4 are ) rolonged 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 dorsallv ; on either side oi the median dorsal line of each 

 segment is a ]>air of blunt tubercles which in other species (E. fragilis 

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

 these segments are directed forwards as spiny ])rocesses. The abdo- 

 minal segment is loughly triangular in form, terminating in an 

 obtusely pointed extremity ; just in front of the articulaticm i.f tiie 

 urojioda is a short lateral process on either side ; the antero lateral 

 mar>:ins are jirolonged into short, flattened, spiny processes corre- 

 sponding with those upon the thoracic segments. 



The aiitenree are rather more than twice the length of the body. 



The uropoda are biramose and very minute ; the inner branch 

 shorter and more slender than the outer branch. 



Statiou KiS, 1100 fathoms.
