able lake was found in 1841, extending above a quarter of a mile 

 into its numerous branches. In this subterranean sea, which rises 

 and falls according to the varying degree of wetness of the seasons, 

 were found a fish and a crustacean, both colourless, with eyes 

 concealed under the skin, like the Proteus. Various communi- 

 cations have been made to periodicals in North America and 

 England concerning the former,* which is introduced under the 

 name of Amblyopsis spelceus in the splendid Natural History of 

 New York, published under the authority of that State, and the 

 zoological part of which belongs to James Dekay.f Dr. Tell- 

 kampf, a German, who visited the cave several years later, has 

 given a further account of its Fauna since his return to Europe, 

 in two memoirs. J According to researches instituted partly by 

 the celebrated J. Miiller, this fish is represented as the type of a 

 new family, Heteropygii, but nothing of consequence is said as to 

 the anatomy of Astacus pellucidus, which name indicates that it is a 

 congener of the river Crustacea ; an opinion which Thompson had 

 previously pronounced, without, however, scientifically supporting 

 it. Our author has discovered several new Articulata, of which 

 he describes the following : — Adelops hirtus of the family Stlphidce, 

 being a new genus and species, which he distinguished from 

 Choleva solely by the want of eyes, and which in fact would be- 

 long to that genus, unless, which is probable, the essential syste- 

 matic characters of the animal have been overlooked : Phalango- 

 des armata, a small Arachnidan of the family of Oplltones, white, 

 blind, differing from the other forms by its aculeated palpi : 

 another small, blind, white Arachnidan, Anthrobia Mammouthia, 

 concerning which Dr. Tellkampf 's account affords us no means of

 agrees with Milne Edwards's description of Astacus Bartoni, an inhabitant of the 

 Delaware and other American rivers, and that it possesses eyes ; crickets also 

 (as they were termed) were captured seven miles within the cave. They like-
