602 REPORT 1863. 



maturely closed investigations of Dr. Kennerley are only the beginning of a 

 rich harvest. Dr. George Suckley, late assistant-surgeon of the U. S. army, 

 was appointed to complete the natural-history work, after his lamented 

 death. A complete list of the species collected will be found in the fifth column 

 of the Vancouver and Californian table, v. infra, par. 112. The particulars 

 of station, &c., and all the knowledge which the laborious explorer had col- 

 lected, are lost to science. It is quite possible that some of the species here 

 accredited to Puget Sound were obtained in neighbouring localities in the 

 Straits of De Puca. The specimens are in beautifully fresh condition, and 

 of most of them the animals were preserved in alcohol. The following are the 

 shells first brought from the Vancouver district by the American N. W. 

 Boundary Commission, the diagnoses of new species being (according to 

 custom) first published in the Proceeding's of the Ac. Nat. Sc. Philadelphia. 



No. 



1. Zirphcea crispata. Two living specimens of this very characteristic Atlantic sp. 



2. Saxicava pholadis. Several living specimens. 



3. Sphania ovoidea, n. s. One sp. living. 



4. Cryptomya Californica. Several living sp. 



5. Thracia curta. One specimen. 



G. Mytilimeria Nuttallii. Three sp. living at base of test of Ascidian. [The animal 

 appeared too peculiar to venture on a dissection. It has been entrusted to 

 Dr. Alcock, of the Manchester Museum.] 



7. Ne&ra pectinata, n. s. One sp. living. 



S. Kennerliafilosa, n. s. and n. subg 1 . Several living specimens. 



9. Psammobia rubroradiata. One Afresh specimen of uniform tint. 



10. Macoma (?v.) expansa. Adult broken ; young living. Belongs to a group of 



forms classed together by some writers under lata or proximo, but the cha- 

 racters of the hinge and mantle-bend have not yet been sufficiently studied. 



11. Macoma yoldiformis, n. s. One valve. 



12. Angulus modestus, n. s., but closely allied to the eastern A. tener, Say. Two 



sp. living. 

 126. Angulus (?modestus, var.) obtusus. Several fresh specimens. 



13. dementia subdiaphana, n. s. Very rare, living. Intermediate between de- 



mentia proper and the prora group of thin Callistee. 



14. Psephis Lordi, Baird. Several living sp. from which the subg. was eliminated. 



15. Venus Kennei'lyi, Rve. Very rare. One sp. living. Some of the shells called 



V. astartoides by Midd. may be the young of this. 



16. Petricola carditoides. Several fresh specimens. 



17. Astarte (? var.) compacta. One sp. living ; may hereafter be connected with A. 



compressa. 



18. Serripes Grcenlandicus. Several young living specimens. 



19. Lucina tenuisculpta, n. s. Two living specimens, of which one had the surface 



disintegrated. 



20. Cryptodon serricatus, n. s. One living sp. 



21. Kellia Laperousii. A few living specimens. 



22. Kellia suborbicularis. A few living specimens. 



23. Lasea rubra. One sp. living. 



24. Pythina rugifera, n. s. Two living sp. Intermediate between Pytltina and 



Kellia. 



25. Tellimya tumida, n. s. One sp. living. 



26. Modiolaria lavigata. Two living sp. 



27. Mo'diolaria marmorata. One sp. living. (A shell in the U. S. E. E. Col., 



though marked "Fiji" in Dr. Gould s MS. list, probably came from Puget 

 Sound, being thus confirmed.) 



28. Nucula tennis. Two sp. living*, 



29. Acila castrensis. One sp. living. 



30. Leda fossa, Baird. One normal sp. living. 



* These species were kindly determined by Mr. Hanley.
