clining part of head respectively. The dorsal has 22, the anal 18 
rays, the last ray in both fins is divided down to the base.

The Astrodermus-forms were hitherto known only from the 
Mediterranean, if, however, the supposition is right that these 
forms are young stages of Luvarus imperialis whose distribution 
is nearly universal in all warm seas, a wider range of Astro- 
dermus is to be anticipated. The specimen in question from Mo- 
sambique is therefore of interest in this connection, giving another 
evidence in support of the correctness of the said identification. 
Luvarus imperialis being known from Australian waters, the oc- 
currence of a young stage at the coast of Mosambique by and for 
itself is not so remarkable, nor that the Indian Ocean is to be 
included in the area of distribution of this species. I find no cause 
for having any doubts as to the correctness of the locality of this 
specimen. In the era of the sailing vessels the Bergen Museum got 
various material which seamen brought home for the museum, 
— glass and spirits being often distributed by the museum for such 
purpose. |
