 is then as follows : —

C and Q are both females, and if the specific identity of the former with the 

 males A, B^ and E be allowed, there is obviously nothing in the number of the 

 scales to separate A. lophotes and A. laterna. 



As to the colours, we have already noted the existence of a black patch on the 

 ocular pelvic, which appears, throughout the series, to be confined to males. The 

 specimens A and B [A. lophotes s) are sufficiently perfect to show the colours of 

 the ocular side, which, in spirit specimens, consist of a greyish brown (darkest, on 

 account of the peritoneal pigment over the abdominal region) mottled all over 

 with dark grey and black markings, of which the larger show a tendency to 

 arrange themselves along the interneural regions and the lateral line. The lips 

 and jaws are dark grey, with dark markings, and the rays of the dorsal, anal, 

 caudal, and pelvic fins are banded with black, except on the extremities of the 

 elongated rays. Dr. Giinther ("P. Z. S.," 1890, p. 40) supposed that the 

 markings shown in Day's figure of the Lundy Island specimen of A. lophotes 

 (" P. Z. S.," 1882, pi. liii.) were reproduced from a veritable example of 

 A. Grohmanni, the species with which Day identified it. Comparison with a 

 specimen of A. Grohmanni in our possession shows that this might be the case 

 without much imparing the value of the figure, as A. Grohmanni differs from 

 A. lophotes chiefly in having a somewhat darker head. The specimen C has the 

 lips and jaws a good deal lighter than in the lophotes males, and the fin-rays are 

 only feebly banded with pigment. 



The Norwegian female has the ocular side a uniform brownish grey 

 (darkest over the abdominal and ovarian region) very faintly marbled with a 

 darker shade. The jaws are rather pale, and the fin-rays are only faintly pigmented. 

 This last condition seems to hold good for all the A. laterna series, which are 

 otherwise too much injured for satisfactory observation of the pigment. 



After we had completed the examination of the Survey and other specimens 

 mentioned above, Mr. Cunningham most generously placed at our disposal a large 

 series of examples from Plymouth. These comprised 12 typical A. lophotes males, 

 and six large females, showing the slight elongation of the anterior rays, similar 

 to the female D of the Irish series. In addition there are seven smaller examples, 

 five males and two females. This augmentation of our material was most valuable, 

 since it eliminates from our work a great part of the risk which must always
