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.

    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.

    Gastropoda: Naticidae) on Soldier Crabs (Crustacea: Mictyridae)

    Molluscan Research 31(2): 125–132 ISSN 1323-5818 http://www.mapress.com/mr/ Magnolia Press First evidence of drilling predation by Conuber sordidus (Swainson, 1821) (Gastropoda: Naticidae) on soldier crabs (Crustacea: Mictyridae) THOMAS HUELSKEN School of Biological Sciences, The University of Queensland, St. Lucia, QLD 4072, Australia. Email: [email protected] Abstract Moonsnails (Naticidae) are major predators in marine soft substrates worldwide and are thought to prey almost exclusively on shelled molluscs by drilling predation. However, reports on single individuals of various naticid species showing unusual feed- ing behaviour indicate that naticids possibly also feed on other prey which have an external skeleton. The present study pro- vides the first evidence for size selective feeding of an Australian moonsnail (Conuber sordidus) on crustaceans. C. sordidus preys on soldier crabs (Mictyris longicarpus and Mictyris platycheles) on intertidal sand/muddy tidal flats, representing the first well-documented example of a naticid preying on large non-molluscan invertebrates in addition to shelled molluscs. This indicates that prey choice in C. sordidus is less stereotyped than predicted for naticid species, although the feeding mode docu- mented here is similar to that used to capture their main diet of shelled molluscs. The results strongly support some contested earlier studies that have also indicated that naticids will eat non-molluscan prey with an external skeleton, highlighting a need to re-examine generally accepted models concerning naticid feeding ecology. Key words: Mictyris, hermit crab, size-related feeding, behaviour, intertidal, Caenogastropoda, Naticoidea Introduction Some naticids have been reported as showing ‘unusual’ predatory behaviour and possible feeding on non-molluscan Shell drilling molluscs are major invertebrate predators in prey (Table 1).

Kabat, c/o Department of Invertebrate Zoology, National Museum of Natural History, Smith- sonian Institution, Washington, D.C. 20560-0163 U.S.A. Key words: Ambon; Gastropoda; Indonesia; Naticidae; Rumphius. The 1990 Rumphius Biohistorical Expedition to Ambon (Indonesia) made 44 collecting stations. Twenty-seven species representing 11 genera of the Naticidae (Gastropoda: Caenogastropoda) were collected at 29 stations. This paper provides keys to the genera and species, along with diagnoses and short synonymies of the species. The modern identity of the thirteen naticid species known to Rumphius in his “D’Amboinsche Rariteitkamer” (1705) is determined. Fifty described species of Nati- cidae are currently known from Malaysia and Indonesia, with 38 known from Ambon itself (this expedition and older museum collections).
