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. 
12. Careproctus georgianus n. sp. 
(PI. Ill Fig. ii.) 
2 specimens from stat. 32, South Fjord, Cumberland Bay, South Georgia, depth 
195 m., clay mixed with stones, temperature at the bottom + i, 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 2 4 /s 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 1V4 in length of head. Length 
of snout 2 3 /s 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 (63 mm.).
