604 REPORT — 1863. 



ploring the regions south, of the political boundary, similar explorations, on 

 a less extensive scale, were being made under the direction of the Britibh 

 Government. The naturalist to the British North American Boundary Com- 

 mission, during the years 1858-1862, was J. K. Lord, Esq., F.Z.S. He made a 

 very valuable coUeotion of sheila in Vancouver Island and British Columbia, 

 the first series of which was presented to the British Museum. The new 

 species were described by W. Baird*, Esq., il.D., E.L.S., in a paper com- 

 municated to the Zool. Soc, and published in its ' Proceedings,' Feb. li.'th, 

 1863, pp. 66-70. — Another series of shells, from the same district, was pre- 

 sented to the Brit. Mus. by the Lords of the Admiralty, collected by Dr. Lyall, 

 of H. M. Ship ' Plumper.' Two new species from this collection were described, 

 by Dr. Baii-d, in a separate paper, P. Z. S., Feb. 10th, 1863, p. 71. The new 

 species from Mr. Lord's coUeotions have been drawn on stone by Sowerby. 

 The figure-numbers here quoted correspond with the proof-copy kindly fur- 

 nished by Dr. Baird. — A third series was collected by Dr. Forbes, E.N., in the 

 same Expedition. After Mr. Cuming had made his own selections, this passed 

 into the ordinary London market. It contained several species of peculiar 

 interest. The following are the (supposed) new species of the Survey : —

 which is, that the ribs end above the periphery, so that a smooth 

 belt appears round the spire above the sutures.]

* It ia due to the memory of Dr. Kennerley, as well as to the other naturaUats con- 

 nected with the various American surveys, and the officers of the Smiths. Inst., who so 

 generously entrusted to the writer their unique specimens for eompai'ison with the 

 Xiondon museums, to state, that (with two exceptions) the new marine species of tlie 

 British Survey would have been pubhshed long before the appearance of Dr. Baird'a 

 paper, hut for the derangement of the IT. S. natural-history publications, consequent on 

 the secession movement. Although the Smithsonian Inst, had offered to present tu 

 the Brit. Mus. their first series of duplicate specimens from these expeditions, whicli 

 was exhibited at the Manchester Meeting of the Brit. Assoc, where this Report was 

 Qalled for, no notice was given to the writer of the valuable results of the British 

 survey; and it was only through the private kindness of Drs. Sclater aiid Baird that 

 he was prevented from adding to the list of synoi yms, already, alas! so numerous 

 and perplexing. 



f These species are named after places, not after persons, as would be supposed 

 by the terminations. oq
