' The members of tins genus [Munidopsis] have been taken in almost all seas the deep water of which has been 

 explored by the dredge, and they are found at depths varying from about 100 to upwards of 2000 fathoms. The 

 species differ widely among themselves in the form of those parts which in other Crustacea afford generic characters ; 

 and yet it is impossible to effect a natural sub-division, or one which is not founded on a single character to the 

 exclusion of others. It is probable that the loss of sight is compensated by a greater development of the tactile sense, 

 and in some species this is evidenced by the great length of the antennal flagella, which in all ]>robability enable the 

 animal to grope its way about on the bottom. — (Henderson, Zool. Chall. Exp., part 69, p. 148.) 



- Whether I am right or not in considering the specimens collected at Stations 146 and 147 {Colossendeis gracilis), 

 Station 298 (Colossendeis media), and Station 325 (Colossendeis hrevipes), as three different species can only be ascertained 

 by examining a larger number of specimens than are at my disposal. I can only point out here tlie great affinity of 

 these different specimens. — (Hoek, Zool. Chall. Exp., part 10, p. 73.)
