Trochus. P. Fischer has completed the monograph of this genus in 
Kiener’s “ Species general.” He describes 253 species, and divides them 
into 43 groups (pp. 414-423), most of them already named by Gray, H. 
& A. Adams, &c., and adds 70 coloured plates (Nos. xliv., xlvii.-xlix., 
liii., liv., Ivii.-cxx.) to those published without descriptions about thirty 
years ago. Only the new species or those not before figured will be 
mentioned infra, but the attention of conchologists may be called to the 
many rectifications in synonymy contained in this valuable monograph.
