The sole character wliich separates Bhinonemus 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 cimhrius (Linn.), but are willing to accept provisionally the 

 name Ehinonemus cimhrius. We have examined numerous specimens 

 which puq)orted to belong to Ciliata argentata (Eeinh.) Gill, and have 

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

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

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

 lish ichthyologists now regard Ciliata 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 0)ios mustela (Linn.), Onos tricirratus (Bloch), and Onos maculatus 

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

 as well as that they are distinct from Onos ensis (Reinh.) GiU, described 

 from the coast of Greenland. 



The synonymy of Onos cimhrius is given below.

By OEOKOE IV. LA^FRENCE. 



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

 fore i)ai*t 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. His 

 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 indicated by quotation-marks.
