Book excerpt: Excerpt from Catalogue of the Collection of Mazatlan Shells: In the British Museum "The Collection, from which the shells described in the following pages have been carefully selected, was made at Mazatlan, (lat. 23 N., long. 107 W.) during the years 1848-50, by a Belgian gentleman named Frederick Reigen." The bulk of that portion of it quoted in the following pages as the 'Liver-pool Collection, ' was purchased by Herbert Thomas, Esq., of Bristol, and Mr. P. P. Carpenter. The latter gentleman "selected from it as many specimens as might be required (1) to illustrate the local-fauna of a known station at the mouth of the Gulf of California; and (2) to exhibit the amount of variation, whether great or little, observed in comparing together large numbers of individuals in the various species. The latter object appeared of no slight importance, especially for the sake of inland naturalists; who have usually to depend on the very limited number of specimens which are generally to be seen both in public and in private collections." This series Mr. Carpenter presented to the British Museum, on the understanding that it should be kept separate and intact for the purposes above named, like the Cuban, South American, and other local collections: he undertaking, at the same time, to prepare a Descriptive Catalogue, which is here printed. The descriptions of the Bryozoa, occupying the first six pages, were kindly communicated buy G. Busk, Esq. F. R. S., &c. "The collection consist of about 8873 specimens (2505 Bivalves, &c., and 6368 Univalves) mounted on 2530 glass tablets. The number to the left refers to the species, that to the right to the tablet in the Catalogue. The minute specimens are fastened on strips of thin glass enclosed in test tubes. By this mode of arrangement, both sides of the object can be seen without disturbance." "The measurements (unless otherwise expressed) are thus taken. In the bivalves; long. from the umbo to the middle of the ventral margin; lat. from the anterior to the posterior ends; alt. the thickness of the closed valves.
