Of crustaceans the fresh-water ponds have yielded a Branchipus, some 
Gammaride, one Daphnia, and one or two other almost microscopical 
species, which, I think, belong to Cyclops. 
I ean hardly write anything about the fishes inhabiting the rivers and 
lakes, It will be better to postpone this topic until next year, and I 
shall limit myself to a mere enumeration of the species observed by me 
up to date, viz, Gasterosteus pungitius L., and G. cataphractus (Pall.), 
Salmo callarias (Pall.}, (called Goletz by the natives here), Oncorhynchus 
lycaodon (Pall.), (Russian, Krasnaja Riba), O. sanguinolentus (Pall.), (Rus- 
sian, Kisutch),O. proteus (Pall.), (Russian, Gorbuscha), and the ‘‘Bajdarsik” 
of the natives, which I have not yet been able to make out. ‘“ Sik” is 
the Russian name of Coregonus, but I do not believe that it belongs 
to that genus, as the mouth extends beyond the eye. Probably it is 
the same species called Coregonus by Nordenskjéld (Vega Expedition, 
American edition, page 618), as Ido not know any other one to which 
to refer this name; the three other species of which he speaks are calla- 
rias, lycaodon, and proteus. 
In my next report I hope to be able to add another Salmonoid to the 
list of the species known (as I suspect the occurrence of such a one). 
Batrachians and reptiles are wanting altogether on the island, as 
might be expected. Dr. Dybowski and I have been searching very 
eagerly for a Salamandrilla, as we suspected the “ Kragani,” of which 
the natives told us, to be such an animal. It turned out, however, to be 
a large Dytiscus. 
The ornithologist starting for Bering Island will probably prepare 
himself beforehand for hunting and collecting two large, rare, and inter- 
esting birds, viz, Thalassaétus pelagicus (Pall.) and Phalacrocorax perspi- 
cillatus Pall.,as Pallas, on Steller’s authority, gives LBering Island as 
their proper habitat, where they occurred in abundance. You will not 
be more disappointed than I am in learning that there is no hope what- 
ever of getting a specimen of the latter, and very little of obtaining 
any of the former from Bering Island. 
It is not to be doubted that the Phalacrocorax perspicillatus does not 
occur on the islands at present. The natives, however, remember very 
well the time when it was plentiful on the rocks, especially on the out- 
lying islet Are Kamen. About thirty years ago, they say, the last ones 
were seen, and the reason they give why this bird has become extermi- 
nated here on the island is that it was killed in great numbers for food. 
They unanimously assert that it has not been seen since, and they only 
laughed when I offered a very high reward for a specimen. 
When Pallas gives Bering Islandas the habitatof the Thalassaétus I feel 
tolerably sure that he has misunderstood Steller’s words, or that Steller, 
if he really has reported its occurrence, met with only a straggler from 
Proce. Nat. Mus. 83 dD
