My friend the Rev. T. R. R. Stebbing, F.R.S., was kind enough 

 to identify and count the specimens of this species. It would no 

 doubt have occurred in more of the surface hauls had not my 

 finest tow-net been devoted to the collection of Diatoms for the 

 Scottish Fishery Board. It is no doubt a purely epiplanktonic 

 form in the Faeroe Channel ; a single specimen only was taken at 

 20 d (500-400 fathoms) as against about 106 specimens in 7 hauls 

 at the surface ; the single deep specimen was probably a sinking 

 corpse. 



This species is, I believe, known only from the surface l ; it 

 ranges over the Baltic, Norwegian coast up to Yadso, Denmark, 

 Boulogne, Concarneau, Trieste. 



OSTRAGODA. 



The representatives of this order belonged exclusively to the 

 Halocypridse, and were mostly taken in the mesoplankton. Only 

 one species, Concho&da maxima, occurred sufficiently often to allow 

 of a generalization as to its horizon. 



The identification of a Halocyprid is rarely satisfactory without 

 dissection of the mouth-parts, which means destruction of the 

 specimen. I have, however, dissected a considerable number, and 

 feel at all doubtful only in the case of C. porrecta ; I have pre- 

 ferred, however, to leave the specimens under this species rather 

 than create a new species on the strength of slight differences 

 in the armature of tjie mandible. 



The table following shows those surface and deep-water hauls, 

 made by Professor Chun between Finistere and the Canary Islands 

 with open vertical nets 2 , which contained the same species as
