Till-: ANNALS AND MAGAZINE OF NATURAL HISTORY. [Frr.HTFI SKIIIES.] No. 33. SEPTEMBER 1910. XXVTII. — .1 Survey of the South-African Sfenogyrinap, toith Descriptions of several new Species. By M. CONNOLLY. [Plate VI.] Ever since Krauss, in 1848, descriljed, under the names of Bulimus turriformis and B. linearis, specimens of shells brought by J. A. Wahlberg from Natal and Mt. Mohapaani respectively, there has existed some confusion regardin^j; them, which has rendered difficult the task of differentiating be-tween them and other closely allied members of their family which abound over a great part of the Dark Continent. Both Krauss's descriptions can be and have been applied by different authorities to totally different species from widely divergent localities, while his figures do not sufficiently brin-^ out the details lacking in his descriptions. Thanks to the courtesy of Dr. iSigalmar Th6el, of the Royal Aciidemy of Stockholm, I have been privileged to examine original specimens collected by Wahlberg and determined by Dr. Krauss. The results are of considerable importance, and would alone justify the appearance of a paper on the subject. The determination of Krauss's species leaves without names several forms, some of which have been long known Vi collectors, but more or less inaftpropriately ret'crred by them to turriformis or lintaris.
