XOKTII ATLANTIC SEA AND THE FAROE CHANNEL. 117 



Gardiner's Maldive collection, nor does Scott mention its occurrence in 

 Professor Herdman's collection of Ceylon Copepoda. 



9, Faroella multiserrata {nov. gen. et sp.)* Slender two -pointed 

 rostrum ; head fused with first segment, but last two segments of the 

 thorax more or less completely divided, the posterior segment with long 

 lateral spines. Anterior antennte with eighth and ninth joints fused, 

 but the twenty-fourth distinctly separate from the twenty-fifth. Man- 

 dibles with exopodite shorter than the endopodite ; posterior foot-jaws 

 with endopodites not more than half the length of the exopodites ; first 

 feet with one-jointed endopodites, second pair two-jointed, the terminal 

 saws of the feet distinguished by an extraordinary number of fine and 

 closely-set teeth (69-70). Size of the ? 3-54 mm. and over, the <? about 

 the same. (PI. IX., figs. 26, 27, 28.) 



It is not uncommon in the deep water of the Faroe Channel, and has 

 been traced by the writer as far south as Valentia in Ireland. 



10. Chiridius Vanhoffeni {nov. sp.). One example only of a <? , which I 

 think to be identical with the Pseud oml amis armatus described by Yan- 

 hoffen (Ch'djdand Exped., 1891, II. Bd., Berlin, 1897), was taken in the 

 Faroe Channel. Length 3'1 mm.; head without rostrum, and last thoracic 

 segment produced into short spines ; anterior antennte of twenty-three 

 joints ; posterior antennse with the outer ramus twice as long as the 

 inner ; mandibles with endopodite only half the length of the exopodite, 

 the masticatory plate wanting; anterior foot-jaw almost obsolete, the 

 posterior foot-jaw with the endopodite more than half the length of the 

 second basal ; maxilla retrograded, inner lobes nearly obsolete, exopodite 

 large and with ten bristles ; first pair of feet with one-jointed endo- 

 podite, second pair with two-jointed endopodite ; fifth pair of one 

 ramus on each side, each of five segments, the right foot the longest ; 

 two short basal and three slender terminal joints, the last ending in a 

 delicate curved stylet process ; the left foot with larger basal joints, of 

 the three distal the proximal the largest, the distal short, spatulate, 

 and haired on the inner margin, (PI. IX., fig. 3.) 



In the difierent segmentation of the feet and in other particulars this 

 Copepod differs from CIi. ohtusifrons, of which it might be the hitherto 

 unknown S . It is certainly not a Pseicdocalanus, and though there 

 must always be hesitation about giving an unknown c? specific rank, 

 it does not agree with any genus except Chiridius, and provisionally, at 

 any rate, must be distinguished from other species. 



* This is probably identical with the species described by Sars as ^tidiopsis. His 

 description is, however, rather meagre, and as the writer's descriptions and lithographed 

 plates were prepared for publication two years ago, but have been held over for completion 

 u!' his monograph, he retains tlie name originally given to this genus and species.
