522 Notices of Memoirs — Caucasian Museum^ Tiflis. 



Figs. 13, 14, and 15 are referred to Turrilepas (?) Jilosus, n.sp. 

 A recent examination of the plates of that genus suggests to me 

 that the note of interrogation is fully justified. 



Aurivillius considered that Pollicipes signatus showed a closer 

 approach to the Balanidse than any other of the Lepadidse, but he 

 too, in ignorance of the Devonian Protohalanus, Whitf., discoursed 

 needlessly about the gap in the distribution. Now that the range 

 of the Lepadidee has been extended to the Ordovician, we may look 

 confidently for further discoveries. We may also hope that the 

 time has now come when even the textbooks may awake to the 

 fact that the genera Pollicipes and Scalpellum existed in Palaeozoic 

 times. 



My apology for insisting on this is not merely that both 

 Dr. Aurivillius and Professor Lindstrom, who supplied him with 

 the material, have unhappily passed away, but that I had the good 

 fortune to be the discoverer of the beautiful specimen of Pollicipes 

 signatus, when developing a specimen of Gissocrinus verrucosus from 

 the Pterygotus bed of Wisby Waterfall, in May, 1891. The very 

 fragile specimen was subsequently licked into shape (no metaphor 

 is intended) by Mr. G. Liljevall, to whom the excellent drawing of 

 it is due. 



VI. — The Caucasian Museum, Tiflis, is publishing a complete 

 Catalogue of its Collections, in both the Russian and German 

 languages, the title in the latter tongue being : " Die Sammlungen 

 des Kaukasischen Museums im Vereine mit Special Gelehrten 

 bearbeitet und herausgegeben von Dr. Gustav Eadde, Direktor, etc." 

 The catalogue is in the form of quarto volumes, in boards, measuring 

 31x23 cm. Volume III, which has been sent to us for review, 

 deals with the geological collections, and is by Professor N. I. 

 Lebedev. It consists of xii + 322 pp. and 8 plates. The material 

 is arranged under the heads of the several collections, which are 

 classified quite roughly, apparently following the localities in the 

 order in which they were visited. Among the collections that of 

 Abich from Daghestan is one of the most famous ; this is accompanied 

 by a descriptive catalogue which is in greater detail than the present 

 one and will be published in extenso in MittJieilungen des KauTcasisclien 

 Museums. There are also donations by successive chiefs of the 

 Office of Mines; the collections of F. Bayern, chiefly of value for 

 the exactness of the localities given, and worked over by Arzruni, 

 Valentin, and Lebedev ; other collections that have afforded material 

 for the writings of these geologists, of Simonovitsch, and others. 

 The preceding are all local, but there are also collections serviceable 

 for comparison, especially those from the Crimea, Bessarabia, and 

 Transcaspian, as well as a fine series from various horizons and 

 localities in Western Europe, partly purchased and partly the gift 

 of Mr. J. de Morgan. The present catalogue does not profess to 

 be much more than a rough list, and, as is only natural in a work 

 produced under such disadvantageous conditions as regards literature 

 and the help of specialists, the determinations are clearly lacking
