THE NAUTILUS. 59 



far enough to show the general quality of the work. The figures are 

 all bad copies, as well as most of the descriptions ; and such classifi- 

 cation as there is is only right by accident ; such cases being readily 

 accountable for by the law of chances. If it were only a reasonably 

 careful compilation, tiie work might still have a certain value; but 

 it abounds with minor blunders, such as " Chiton sowerhyanhis " for 

 C. sowerbyanus, " Port Jankson," " Ciiiton goodalii," etc.; but per- 

 haps the most amusing case in the part just issued is that of Chiton 

 sulcatus Wood. This is renamed Chiton Woodii Cles., and said to 

 be from " Lord Woods Insel der Gallopagos." The new name is of 

 course quite unnecessary, because Ch. sulcatus W^ood dates from 

 1814, some years prior to any other use of that specific name. The 

 new name Chiton (CaUochiton) Carpenteri Cles. (p. 64), is a syn- 

 onym of Callistochiton pulchellus Gray, besides being pre-occupied, 

 see p. 25 of the same work. When the monograph on Scaphopoda 

 in tlie Conchylien Cabinet was issued, I thougiit that for blunders and 

 general inadequacy it could not be surpassed ; l»ut the work on Chi- 

 tons, by the same author, promises to be a close second. — H. A. P. 



Zweiter Beitrag zur Binnen-conchylien des Miocdns von Oppeln in 

 Schlesien. — Von Prof. Dr. A. Andrefe. Hildesheim, Dec, 1902. 

 In this further study of a Miocene land-shell fauna. Prof. Andreae 

 brings out several novelties of unusual interest. Tiie new group 

 Gyralina contains Hyalinia (G.) roemeri n. sp., a form very similar 

 to our Helicodiscus lineatus. There is a new species of Strobilops, 

 described under the name Strobilus. Also several interesting Heli- 

 ces. Adelopoma martensi n. sp., is a minute Diplommatina-Iike 

 form, in which relation is found with South American species de- 

 scribed under the genus Adelopoma of Doering, ranging from Argen- 

 tina to Guatemala. In tliis connection it may be well to call atten- 

 tion to the fact tliat forms of the same genus occur in eastern Asia. 

 ^'- Diplommatina'^ pusilla Mart, of Japan, and its variety omiensis 

 Pils., which are placed by Kobelt (Tierreich, Cyclophoriden) in 

 Cylindropalaina, really have all tiie shell characters of Adelopoma. 

 Also D. amurensis Mouss. (Journ. de Conchy)., 1887), from Vladi- 

 vostock, which is apparently identical specifically with pusilla Mart. 

 Another German Miocene species, Diploinmatina dietzi Flach, is re- 

 ferred by Dr. Andrea? to Adelopoma. The distribution of tlie genus
