 Occurrence. The "Ingolf has taken this species at 8 localities: 

 Davis vStraits: St. 36: 6i°5o'N. L., 56°2i'W. L., 1435 fni; i spec. 

 South of Greenland: St. 21: 58° 01' N. L., 44° 45' W. L., 1330 fni; 2',, spec. 

 West of Iceland: St. 12: 64° 38' N. L., 32° 37' W. L., 1040 fm.; ca. 20 spec.

The species has been taken bv the "Thor" three times to the south of Iceland and once south- 

 west of the Faeroes; for two of these the apparatus used was the young-fi.sh trawl with 1800 meters wire out. 



Distribution. As Sars has mi.xed together 3 species (E. aiisf rails Dana, E. Hugiticiilata Will.-Suhm, 

 and E. sculpticauda Faxon) in his description of E. aitslrnlls and as later authors have not described 

 the .specimens examined bv them I shall not follow the literature in .speaking of the distribution but 

 base my statements on my own observations. In 1905 it was twice taken 1)\- the "Thor" west of the 

 Hebrides with 1500 meters wire out; I have seen numerous specimens from the western Mediterranean, 

 from the Atlantic round the Azores and Canary Islands, from various places in the Indian Archipelago 

 and from parts of the Pacific Ocean. To judge from the catclies of tlie "Thor" and of G. H. Fowler 

 (1905) this species is always pelagic in intermediate layers; it never comes near the surface. 



Remarks. In the paper cited above I have indicated the characteristics of this species which 

 distinguish it from the real E. auslralls Dana and from another large form as >-et unnamed, and also 

 discussed the synonymy. — 



Adult specimens are as a rule only ca. 27—30 mm. in length, but two specimens of cpiitc 

 unusual .size, viz. a female with marsupium 37 mm. long and a male 38 mm., occur amongst the 

 considerable material from the •'Ingolf St. 12.
