 In Senate Executive Dun/mint STo. 146, Fiftieth Congress, second session. Washington, Gov- 



ernment Printing OfiBce, 1889. 

 These comprise: (1) Letter to Mr. Mooro, Third Assistant Secretary of State (<>;>. cil., pp. 

 2-4); (2) Letter to Mr. Bayard, Secretary of Slate {op. fit., pp. 10-12); (3) Letter to Mr.

 ary (op. cil., 13-23); (•">) Supplementary memorandum on the views of General Cameron, 

 as submitted in the letter of Dr. George M. Dawson to Sir Charles Tupper in regard to 

 the Alaskan Boundary (op. cit., pp. 23-28). 

 These documents discuss the wording and true intent of the treaty in which the boundary of 

 the Territory of Alaska is defined, and criticise a construction of it put forward on behalf 

 of certain claims of the Dominion of Canada.

 with an account of a remarkable sexual modification of the epipodium, hitherto

This article describes the soft parts of this abyssal species, aud shows that the right anterior 

 epipodial lappet is rolled up and peculiarly modified to serve as a seminal conduit.

This points out that the whole group of Ameria is distinct from the Physidce, and a glance at 

 the tentacles of the living animal should be sufficient to determine whether it should be 

 referred to the Limnceidoe or the Planorbidop..

This article determines for the first time the soft parts of this subgenus, points out that the 

 hinge is destitute of lateral teeth, and describes a now species from Lower California, L' 

 annetton, dredged by the U. S. Fish Commission in 1888.

 bean Sea (1879-'80) by the U. S. Coast Survey Steamer Blake, Lieut. Commander

 ing, xxix. Report on Mollusca, by W. H. Dall, Part n. Gastropoda and Sca- 

 phopoda. Cambridge, the Museum, June, 1889. 492 pp., 8vo. Plates x-xl. 



In this paper about 470 species and varieties collected by the Blake are enumerated, discussed, 

 and described, or compared with others obtained by the U. S. Fish Commission from the 

 same region. Three hundred and eighty-five species and varieties and 30 genera, sub- 

 genera, or sections aro treated as new. A large amount of new information in regard to 

 the anatomical characters of the Mollusks referred to is contained in the report, together 

 with the revision of the synonymy of many of the species of the coasts of the United 

 States. 

 Perhaps the most interesting data are thoso relating to the anatomy of Plcurotomaria ,■ of the 

 bivalves belonging to the families Poromyidce, Dimyidce, Verticordiidce, and Cuspidariida-, 

 together witli the description of recent genera like Conomitra. Dolophanes, Mesosioma, 

 Diastoma, Mesorhytis, and Dolichotoma, hitherto known only as Tertiary fossils. The i lu- 

 cidation of the characters of the animal in Aurinia, Scutellina, Capulus, Turcicvla, etc., 

 and the determination of the presence of a verge in many lihiphidoglossa is also an 

 addition to knowledge of much interest.
