Tlie sole character whicli separates BMnonemus from Onos is the pres- 

 ence of a nasal cirrus, a character to which we are unwilling to allow 

 more than a subgeneric value. We believe that the species should be 

 called Onos cimbrius (Linn.), but are willing to accept provisionally the 

 name Rldnonemus cimbrius. We have examined numerous specimens 

 which jiurported to belong to Giliata argentata (Reinh.) Gill, and have 

 found them in every case to be the young of this species, for small indi- 

 viduals of R. cimbrius are found swimming at the surface, although the 

 adult fishes inhabit only the deeper parts of Massachusetts Bay. Eng- 

 lish ichthyologists now regard Oiliata as the larval form of "Motella," 

 and if this be not the case, we doubt if this genus has ever been ob- 

 served in the Western Atlantic. The National Museum has specimens 

 of Onos mustela (Linn.), Onos tricirratus (Bloch), and Onos maculattis 

 (Risso); the specific individuality of the latter two seems very doubtful, 

 as well as that they are distinct from Onos ensis (Reiuh.) Gill, described 

 from the coast of Greenland. 



The synonymy of Onos cimbrius is given below.

After completing the exploration of Grenada, Mr. Ober left there the 

 fore part of April and visited the island of Tobago, where he remained 

 for more than two months, and did not arrive in Martinique until the 

 beginning of July, remaining there until the latter part of August, llis 

 collection was made "from July 9th to August 20th." It consists of 

 ninety-one specimens. 



He gives an interesting account of the island, which, with his other 

 observations, are mdicated by quotation-marks.
