NOETH SIDE OF THE BAY OF BISCAY, AUGUST, 1906. 3 



fine sand in about 240 fathoms of water, and a single specimen (108 mm. 

 long) at Station XII. on similar ground at about the same depth. 



Onus sp. 



Six specimens of a tricirrate Onus from 60 to 109 mm. long from 

 Station VII. cannot at present be satisfactorily referred to any described 

 species and, in view of the difficulties attending the satisfactory deter- 

 mination of isolated specimens belonging to this genus, it seems best to 

 await further material before applying any name to them. 



Drs. Schmidt and Jensen have kindly compared the specimens with 

 0. Rcinhardti of a comparable size, and inform me that they certainly 

 do not belong to that species, while they also appear to be distinguish- 

 able from 0. Carpentcri, Gthr., and 0. macrophthalmus, Gthr. 



The specimens were taken with the Agassiz trawl, which came np 

 filled with large masses of coral. 



Onus hiscaycnsis, Collett. 



Small examples occurred as follows, in each case on sandy ground : 

 Station II. — One, 61 mm. 

 Station IX. — Two, 62 and 54 mm. 

 Station XIII.— Seven, 64 to 48 mm. 



The broken remains of two small fishes from Station XIII. are probably 

 referable to either this or the preceding species. 



Specimens of the size captured appear to have the back ordinarily 

 greyish-brown in colour with obscure marblings of a darker sliade 

 which become less conspicuous with growth. 



Pleuronectidae. 



Arnof/lossus latcrna (Walb.). 



Two specimens, 89 and 40 mm. long, at Station II. (75-80 fathoms)^ 

 and two, 140 and 37 mm. long, at Station XL (146 fathoms). 



The larger example taken at the latter station showed the character 

 of "^. lopliotes" 



Zcuffopterus meffastoma (DonoY.). 



A single specimen of 175 mm. at Station II. and three smaller ones 

 (73-53 mm.) at Station XI. 



Damaged larvse (about an inch long in each case) were taken by the 

 small fish trawl at Stations VIII. (one) and X. (one). 



Sulea variegata (Donov.). 



A single specimen, 110 mm. long, at Station VIII. 



Gobiidae. 



Gohins Jcffrcysii, Gthr, 



A single specimen of 21 mm. at Station X. and fourteen others of 

 32 to 20 mm. at Station XI.
