Notes on Synonymy. — The synonymy of this species is very con- 

 fusing, representatives of different genera having been included in 

 the same species and many other species founded on mere individual 

 variations. Quelch has considered the synonymy with care ; he 

 reduces many of M.-Edwards & Haime's species to synonyms, in- 

 cluding M. heterogyra, M. serrata, M. crassa, and M. labyrinthica. 

 The last of these, however, appears to me to he a Coeloria, while 

 M.-Edwards & Haime include in Cceloria the M . strigosa of Dana, a 

 step which does not seem to me justifiable. M.-Edwards & Haime's 

 types are in the Paris Museum, but my notes on them having been 

 lost, I do not care to express any positive opinion on the value of 

 the series of species. 



The species is restricted to the shores of the West Indies and the 

 adjoining districts. It has been recently quoted from the Tizard 

 Bank ; the specimen on which the record is based is preserved in 

 the British Museum. So far as I can determine it without a section, 

 it appears to be a Leptoria tenuis, Dana.
