up into little spots which at the base of the fins are of a pure 

 white colour, but become darker farther out; even on the 

 ventral fins a single or a few white spots are seen ^). The 

 smaller the males are, the more they resemble the females with 

 regard to colour. The brown colour which by aid of a pocket- 

 lens is seen to arise from a compact crowding of chromato- 

 phores is paler, so that the three characteristic dark transverse 

 bands can appear, and the white spots are less shiny; still at 

 a total length of 67 mm. the white pattern of the fins is yet 

 purer in the males than in the females and is partly broken 

 up into rounded spots. 



The full grown male is not inferior to the males of the 

 Callionymus-species with regard to height and splendid pattern 

 of dorsal fins. 



The urogenital papilla is not on the whole very conspicuous 

 in this Cottoid, but yet perceptibly longer in the male than in 

 the female; in the two specimens of 77 and 78mm. the length 

 of the papilla is respectively 1.5 ($) and 0.75 mm. (Ç). 



The males seem contrary to other Gottoids to be a little 

 larger than the females ; from the above mentioned trawling of 

 the Ingolf-expedition we have 4 males of respectively 100, 94, 

 90 and 89 mm. while the largest female only measured 78 mm. 

 The largest female that I have seen is 85 mm. 



As will be seen by the synonymy-list I have included in 

 this species the Artediellus atlanticus^ classified as a separate 

 species by Jordan & Ev ermann. After an examination of 

 one single American specimen these writers find that it has : 

 «A blunt occipital ridge or spine» while Collett's figure shows: 

 «Occiput with a bony protuberance on each side provided 



This description is given from tlie specimen preserved in spirits. Fig. 9 

 in plate IV in tlie account of the ichthyological results of the Ingolf- 

 expedition will give a notion with regard to the colours of the live 

 specimen, with respect to an exact representation of the mutual pro- 

 portions of the parts of the body this figure leaves not a little to be 

 sired.
