range, and a much-needed index, as the papers extend over a period 

 of several years. A classification into seven sections is offered. 

 These seem in all cases to be excellently founded groups, and de- 

 cidedly useful in classifying some 7o species which now compose 

 the genus. Few if any groups of Helices of similar extent have 

 been so well monographed. The workman-like manner of the per- 

 formance shows Mr. Gude to be an acute observer artel clear expositor. 

 He is a welcome recruit to the first rank of Helicologists.

 FORNIA, with faanal and geographical notes, Proc. U. 8. Nat. Mus. 

 XXII, pp. 139-142. By R. PL C. Stearns, Ph. D. The first list 

 enumerates some 18 species, all aquatic except Succinea ovalis GId., 

 reported from the shore of Heron Lake. A number of noteworthy 

 variations of Limmcea emarginata from Eagle Lake are discussed, 

 shouldered, lirate, patulous and variously distorted forms occurring. 

 The second paper describes Haliotis fid gens walallensis (Nautilus, 

 XII, no. 9).

Dr. Rudolph Bergh discusses the anatomy of various Tecti- 

 branches in the part of the Malacologisehe Untersuchungen, Vol. 

 VII., just issued. He adopts the erroneous spelling Haminaa for 

 Haminea, and retains it in the Bullida, where it does not belong. 

 An excellent account of the anatomy of H. cornea Lam. follows. 

 Cryptophthalmus follows, also referred to the Bullidce, and the 

 anatomy is now first described. The genus Chelidonura is described 

 anatomically, and referred for the first time to the family DoridiidtK, 

 doubtless correctly. This is a most interesting discovery. The
