S4 DISCOVERY REPORTS 



298 (32 mm.), 2063 (32 mm.), and 2064 (32 mm.), while at other stations adult females of over 50 mm. 

 were taken. This difference in size does not appear to be correlated with locality in any way and 

 apparently it is normal for considerable growth to take place long after sexual maturity has been 

 reached. 



Distribution. E. sculpticauda is essentially a warm-water species and has been recorded on many 

 occasions in the tropical waters of the Atlantic and Pacific Oceans. It has occasionally been taken in 

 temperate waters and has been recorded as far north as the west of the British Isles, 1 possibly under 

 the influence of the Gulf Stream. In the southern hemisphere there has been only one previous 

 record as far south as Cape Town. The Discovery records do not extend its known geographical range 

 in the Atlantic, but its occurrence around Madagascar, off Durban and off East London is con- 

 siderably farther south than any previous records in the Indian Ocean. Of the thirty-two stations at 

 which it was taken by 'Discovery' and 'Discovery II', twenty-four are in tropical waters of the 

 Atlantic and Indian Oceans, seven are situated around the coast of South Africa and one is in the 

 North Atlantic, west of Portugal. 



E. sculpticauda is a bathypelagic form and has been taken at great depths. Many of the captures in 

 the Discovery collection were made with nets open to the surface from depths of 2500 m. and less. 

 The greatest depth at which it was taken in a closing net was 2580-2480 m. at station 101 and the 

 least was 950-850 m. at the same station. In each case the haul yielded a single large adult female. All 

 the captures made by the ships were at shallower depths than those recorded by 'Dana' and it 

 is evident that the species has a considerable vertical range in the deeper waters of the warmer regions 

 of the world. At station 2063 two immature specimens of this species were taken in a vertical haul 

 from only 600 m. to the surface.

1 Fage (footnote on p. 60) noted that Tattersall (1939, p. 228) had in error given the northern limit of this species as the 

 east of Greenland based on a record of Stephensen. This record was in fact of E. unguiculata. Unfortunately in Tattersall 

 and Tattersall (1951, p. 112) I repeated this error.
