Remarks. Notes 17, 18, 19, all referring to the specimens caught at St. 8, read as 

 follows : " deep red, rostrum white with pale red tip ", " red, rostrum slightly paler red ", 

 " orange-red, rostrum broken at tip, but whitish ". No. 2, 5 and 6 are recorded as being 

 "bright orange", "bright orange-red" and "bright scarlet" respectively. 



All the present localities lie between about 32!° S and 52^ S, with two stations also 

 in the South Shetlands. Chilton's record (as anonyx) is the most southerly (71 50' S) 

 yet recorded. It is interesting to note that this species was not taken at any station on 

 the homeward journey from Cape Town, i.e. in the Benguella Current along the west 

 coast of Africa, in contrast with the other species recorded below. 



Ovigerous ?$ were taken in April (South Shetlands) and June (north-east of Falkland 

 Islands). 



The largest ?? (no. 13) and the largest S (no. 14) both came from the higher latitudes. 



The least depth at which specimens were caught was 76 m. (no. 14) ; this was a night 

 haul, but at the neighbouring station (no. 13) the species was not caught either by day 

 or by night at lesser depths than 750-500 m. With this exception there is no evidence 

 that the species ascends towards the surface at night. 



Distribution. Atlantic : 54 N-37 N and 14 S-55 S and nearly 72 S, 0-4900 m. 

 Pacific.
