THE PLANKTON OF THE FAROE CHANNEL AND SHETLANDS. 361 



Challengekia zetlandica {n. sp.), Plate II., Fig. 5. 



Shell subspherical and strongly compressed (oval seen sideways) 

 with the usual diatomaceous markings. The peristome is long, and at 

 the base nearly as long as the shell, and ovate, and terminates in one 

 bifid tooth. The whole peristome is strongly directed towards the 

 ventral side. The shell is much longer than Haeckel's Ch. sloggdtii, and 

 the aboral line is rounded, not straight, as in Ch. sloggettii. It differs 

 from both Ch. sloggettii and harstoni in the possession of a single bifid 

 tooth, instead of two parallel teeth. 



The shell is also much smaller than any of the Challengerida with 

 which I am acquainted, being only '053 mm. long and the peristome 

 "03 mm. long. The width of the shell (dorsally) is -03 mm. 



II. COPEPODA.* 



The Copepoda of the Faroe Channel have been briefly reported on 

 by I. C. Thompson for Fowler (Ptesearch Expn. P.Z.S., 1897). In 

 the same paper a list is given of these, with the areas of their vertical 

 distribution. For the present I withhold any comment on these 

 results, my own work in the Faroe Channel not yet being completed, 

 and will only remark that my own captures with Garstang's closing 

 net in the deeper waters of the Faroe Channel have produced results 

 agreeing in the main with those of Fowler. With work which has 

 accumulated during three years it will be readily understood that it 

 must take a considerable time before a complete survey can be given. 

 I append a first list of Copepoda taken during these expeditions : —
