sisting of short Latin diagnoses, witli occasional comparisons 

 of allied species. It is unnecessary to ]}oint out the extreme 

 value of such a work, especially if it be continued year by 

 year, to the isolated student, whose means may not allow 

 him to obtain the numerous works in which these descriptions 

 are published. 



Mr. Crotch has, moreover, with the view of alleviating 

 the difficulties of modern synonymy, published (Cambridge, 

 1871) a very interesting list of all the Geodephaga and Hydra- 

 dephar/a described a.d. 1758 — 1821, referring them to their 

 modern genera. In it, the law of priority has been strictly 

 adhered to; and all species are re-named, whose names were 

 inadmissible when first employed. The following extracts 

 (some few of which have been noticed in the " Annual" for 

 1867) from it may specially interest British Coleopterists : —
