In Malac. Groenl. it is mentioned that a specimen was taken in a fish at Sukkertoppen, a 

 colony in West Greenland at 65" 25' N. L. In 1903 and 1904 it was taken five times by the "Thor". 

 four of these stations are in the deep water south of Iceland, from 62"47'N.L. to 61° 30' N. L., 19"" 36' 

 W. L. to i5"o3'W. L.; at three of these stations at least it was taken pelagically in the young-fish 

 trawd with 1800 to 1950 meters wire out; the fifth station lies "We.st of Iceland: 65° 00' N. L., 28' 10' 

 W. L., young-fish trawl, 1000 meters wire out (depth of sea 1240 meters)". Concerning St. 105 see under 

 distribution. 



Distribution. This species has been taken off the east coast of North .\merica at localities 

 lying between 4i°i3'N. L. and 3i''4i'N. L.; the depths were from 372 to 2369 fm. (vSmithi. One 

 .specimen was taken at 52' 18' N. L., I5°53'W. L. with the pelagic net sunk to 1410 fm. (Caiman). Ort- 

 mann states that it was taken in the Sargasso Sea with a closing net from 690 — 800 fm., and also 

 south of Cape Verde Islands in a vertical haul from — 213 fm., but whether his specimens reallv be- 

 longed to G. rlrgaiis or at least some of them to au\- of the species later established by IJouvier it is 

 impossible to sa\'. Bouvier says on the distribution: Atlantique, Mediterrauee. 



This species is not a l)ottom-form but lives pelagicalh', as a rule certainly in the dee])er layers, 

 sometimes m higher la\'ers. I>ate has alread\' expressed the same opinion regarding the genera 

 Gciniadas and Dr)ithcsicyiiius. It is probabl\' distributed throughout the deeper j.iarts of the Atlantic, 

 but it is lacking in the sea between Norway and Greenland — Iceland — the l-";eroes. As mentioned 

 above a specimen has indeed been taken in that sea at .St. 105, and though this is in all probability 

 correct, it does not show in my opinion that the species lives in the cold area; tlie .sijecinien must 

 have been carried there b)' the Gulf .Stream. 



Remarks. The genus Gciniadas greath' needs re\-ision, and it is to be hojied that Prof. 

 Bouvier will examine the "Challenger" specimens ami more fresh material from the Indian Ocean and 

 the Pacific. Ortmann and especially Caiman have remarked on the lack of agreement and the diffi- 

 culties in connection with the descriptions of the gills in .Smith, Bate and .\k\)ck. It ma\' be added
