the Schizopods collected by the ' Oceana.'' 7 



Thysanoessa gregaria ?, G. O. Sars. 



Specimens occurred in nine hauls, in nets fishing between 

 500-1 700 fathoms and the surface. We have noted {he. cit.) 

 that the specimens diverge slightly from Sars's description 

 of the type. Probably they will prove referable to Hansen^s 

 T. pai-va. 



Slylocheiron Suhmii, G. 0. Sars. 



Synon, See Hansen, Bull. Mus. Ocean. Monaco, no. 30 (1905). 



S. Suhmii occurred in twenty-five out of thirty hauls, 

 in nets fishing between 270-1770 fathoms and the surface. 

 It was one of the commonest Schizopods taken by 

 Mr. Murray, who collected it in British waters for the first 

 time. Several larvse of this species in all stages of develop- 

 ment were also captured during the cruise. 



Stylocheiron abbreviatum, G. O. Sars. 



Synon. S. chelifer, Cliun. 



A single male example of this species, measuring 20 mm., 

 occurred in net 5 h, fishing from 1410 fathoms to the surface. 

 This is much larger than Chun's specimens, which measured 

 only 14 mm., but examples of nearly equal size were captured 

 by Dr. Fowler in the Bay of Biscay. 



Katerythrops Oceana, H. & T. 



This is one of the new species taken by the 'Oceana.' 

 Descriptions and figures which have already appeared (H. & T. 

 loc. cit.) are reproduced, and brief diagnoses of the genus and 

 species are repeated below. 



Katerythrops, H. & T. 



Characters of the pleopods in the adult male uncertain ; 

 plcopods of the female unknown. Other characters as in 

 Meteryikrops, S. I. Smith, except : — 



Antenna! scale considerably reduced in length in proportion 

 to peduncles of antenna and untennnle, narrow and feeble, its 

 outer margin naked, entire, terminating in a small spine, seta 

 feiv, confined to the apex and distal third [approximately) of 

 the inner margin. 



Telson possibly without the median sette.
