ZOOLOGY: 
ANTARCTIC DEEP-SEA FISHES. 
By G. A. BouLencEr, F.R.S. 
As the meagre information to hand up to quite recently is to be 
found in the general works of the Challenger Expedition and Goode 
and Bean’s ‘ Oceanic Ichthyology’—the latter being recommended 
for its general scope and portable form—it will suffice to mention 
that the only collection made since the publication of these works, 
that of the Belgica, has yielded very few fishes. Up to the present, 
three short preliminary reports have been issued in the ‘ Bulletin de 
l Académie royale de Belgique’ for 1900, in which M. L. Dollo has 
described three new species obtained by that expedition, each being 
regarded as the type of a new genus :— 
Cryodraco antarcticus (Fam. Trachinide). 
71° 22’. Lat. 8. by 88° 38’. Long. W., 450 metres, 
Gerlachia australis (Fam. Trachinide). 
71° 34’. Lat. 8. — 89° 10". Long. W., 500 metres. 
Racoritzia glacialis (Fam. Trachinide), 
71° 23. Lat. S. — 87° 32". Long. W., 435 metres. 
Although the species may not be numerous, yet the individuals 
may, and in such cases the importance is urged of bringing home 
large series, which should be of use both for adding to the know- 
ledge of individual variations, and for making investigations on the 
anatomy. Most of the deep-sea fishes are known from single or 
scanty specimens only, and many are the generic forms the anatomy 
of which is absolutely unknown through want of material that can be 
sacrificed. If, therefore, the Expedition is provided with an ample 
supply of alcohol, the formation of good series of individuals is in 
every case to be recommended. In fact, in regions such as those 
that will be visited, it might even be recommended to preserve every 
specimen not brought up in too bad a condition,
