Card Catalogue of World-wide Shells by S. D. Kaicher Pack contents index Version 1.0 Paul Callomon Elle Scientific Publications Osaka-fu Yao-shi Suehiro-cho 5-2-1 581-0001 Japan November, 1999 (c) Copyright 1999 Paul Callomon. This work may be distributed for personal or institutional use via download from designated web sites; it may be formatted and reprinted in single copies on the condition that the work remains entire. It may not be sold or republished in any form. This work is not available for purposes of zoological nomenclature. Introduction This is an index of the contents of each of the 60 card packs which make up Sally Kaicher's Card Catalogue. It is designed to allow those attempting to collect entire sets to monitor their progress. An alphabetical index of the Catalogue by species name is already available on the same website as this one. Notes - Cards are listed here in numerical order, with the packs ordered as originally published; where the original author's number modifications are available, these have been adopted. In order to use this index as efficiently as possible, owners of cards are recommended to store them by pack, in numerical order. In order not to preempt any of the revisions of the Card Catalogue currently in preparation, no attempt has been made to correct spellings (even where there are clearly typographical errors) or to revise classification. Kaicher's own subsequent modifications to generic placement are similarly not incorporated here. - In the case of 'replacement' cards, Kaicher gave the card a series number as well as the number of the card it was to replace.

Geological and Agricultural
SECOND ANNUAL REPORT OF THE GEOLOGICAL AND AGRICULTURAL SURVEY OF TEXAS, —BY— S. B. BUCKLEY, A. M., Ph. D., STATE GEOLOGIST. HOUSTON: a. c. gray, state printer. 1876. Second Annual Report of the State Geologist To His Excellency, Richard Coke, Governor of Texas: This second annual report of the geological and agricul- tural survey of the State, is respectfully submitted to your consideration. With many thanks for the aid you have given the work, I remain, yours truly, S. B. BUCKLEY, State Geologist. Introduction In the following pages I have given what I deem to be the most useful things pertaining to the agricultural and mineral resources of the State, which I have obtained during the past year, reserving much geological matter of scientific interestfor a final report. Since the last report, I have bought chemical apparatus sufficient to analyze mineral soils and mineral waters, which will be of great assistance in the future work of the survey. This appa- ratus has only been recently obtained. Austin, March 27th, 1876. 4 The Importance of Geology and Geological Surveys. I supposed that the importance of geology and geo- logical surveys was so well known and acknowleded that it would not be proper here to say anything about their usefulness. Nor should I allude to these things, had I not a few weeks ago, heard one who was called a leading member of the late Constitutional Convention, state in a public speech to that body, that "Geology is a humbug and he knew it to be so." It is strange that all the leading universities, colleges and schools of the civilized world have been teaching a humbug for the last 45 years; and still more strange, that all civilized countries, including every one of the United States, excepting Florida, have had or are having geolog- ical surveys made of their domains; also, the United States Government, during the last 15 years or more, has had and still continues to have geological surveys made of its territories.

ZooKeys 963: 1–36. https://doi.org/10.3897/zookeys.963.52234 Abstract An increase in richness of benthic marine mollusks towards high latitudes has been described on the Pacific coast of Chile in recent decades. This considerable increase in diversity occurs specifically at the beginning of the Magellanic Biogeographic Province. Within this province lies the Strait of Magellan, considered the most important channel because it connects the South Pacific and Atlantic Oceans. These characteristics make it an interesting area for marine research; thus, the Strait of Magellan has histori- cally been the area with the greatest research effort within the province.
