Distance from snout to vent 23 mm. 26 mm. 49 mm. 52 mm. 



Distance from vent to brise of caudal . 18,5 > 20 > 37,5 > 42 > 



Depth of body 8,5 10.5 • 22 ; 24 » 



Length of caudal 12.5 > 14 » 20 > 22 » 



Height of first dorsal 10 > 9 > 11 > 14,5 » 



Length of barbel 5 ' 4-s * 9 ' I r » 



From this is apparent that in addition to the difference in shape of the barbel 

 there are other sexual differences, especially apparent in the greater height of first 

 dorsal in the male, and greater length of ventral in the female.

a'l. Ill Fig. 1 1.) 



2 specimens from stat. 32, South Fjord, Cumberland Bay, South Georgia, depth 

 195 m., clay mixed with stones, temperature at the bottom + 1,45° C. 29th of May 

 1902. 



D. 45—52. A. 42—46. 



Thick anterior portion of the body or distance from snout to origin of anal con- 

 tained about 2Vs times in posterior compressed portion of body counted from origin 

 of anal to end of caudal fin. Length of head about 5 times in total length with 

 caudal. Depth of body a little more than 4 times in total. Diameter of eye about 

 4 times in length of head. Interorbital width about i-:'4 in length of head. Length 

 of snout 2Vs to 3 times in length of head. Snout projecting beyond mouth. Cor- 

 ner of mouth extending to below the anterior third of eye. Teeth simple (not tri- 

 cuspid). Transversal diameter of ventral disk about equal to half the length of head. 

 Vent situated close behind posterior margin of ventral disk, its distance from origin 

 of anal not much shorter than its distance from mouth. Anterior nostril tubular in 

 front of the eye, its distance from the same about equal to half the diameter of the 

 eye or the length of the tube itself. No trace of posterior nostrils. A series of 

 rather large mucous pores along the lower and upper lip, and a pair of such on 

 the snout, about midway between the nostrils and upper labial series. Gill opening 

 narrow, about equal to diameter of eye, reaching to upper end of the base of the 

 pectoral, but not beyond. Pectoral a little shorter than head, very little notched, 

 4 — 5 rays on either side of the ventral disk prolonged into a fringe. Dorsal and 

 anal fin broadly continuous with the caudal which is truncate. Skin very loose, 

 which renders the counting of the fin rays very difficult. The colouration in life is 

 said to have been greyish, semipellucidous. The larger specimen (105 mm.) is darker 

 than the smaller (Ç)}, mm.).
