paper read in 1884 (Trans. Edinb. Geol. Soc. vol. v. pp. 185- 

 191) : lierein the name Palccophonus caledonicus was prefixed 

 to a description of the fossil and a comparison of it with 

 J^. nuncius. 



Of the two known Silurian scorpions the holotype of 

 Palceophonus nuncius alone remains, one of the most valuable 

 treasures of the Swedish State Museum. The even more 

 remarkable specimen oi Palceophomis caledonicus has perished, 

 with many another priceless type, in the ashes of Kilmarnock 

 Museum ; but fortunately we have the authoritative descrip- 

 tion by Mr. Pocock, which must be associated with the name 

 first given by Dr. Hunter. 



BIBLIOGEAPHICAL NOTICES. 



Figures and Descriptions of the Fishes of Japan, induding Riul-iu 

 Islands, Bonin Islands, Formosa, Kurile Islands, Korea, and 

 Southern Salchalin. By Shigeho Tanaka, Instructor in Zoology, 

 Science College, University of Tokyo, Tokyo, 1911. Gr. 8vo. 



Of this, the latest addition to Japanese zoological literature three 

 parts have appeared since April, each part consistiug of one sheet of 

 letterpress and five lithogi'apliic plates. The text is written in 

 Japanese as well as English, No systematic sequence of the species 

 is adopted, the author being apparently guided in his selection by 

 the materials at his disposal, by the degree in which addition to 

 our knowledge of a species is desirable, or by other similar con- 

 siderations. Thus in the three parts published he has treated of 

 twenty-four species from fresh water as well as from the littoral and 

 deep-sea fauna. The descriptions are short, shorn of insignificant 

 detail, and, with the addition of the accompanying excellent figures, 

 perfectly sufficient. 



The work will be of the greatest assistance to the student of 

 Japanese Eishes, whatever its limitation may be finally ; and we 

 trust that the author will bo able to continue it to its completion 

 at a faster rate than he intends at present, viz, at the rate of six 

 parts annually.

Anglers and naturalists should be most grateful to Mr. Began. 

 His book gives clear descriptions, lucid keys, and adequate figures 

 of all the species, and admirably epitomizes all that is sound in our 

 knowledge of their life-history. Classification, necessarily technical 

 in language, is restricted to what a systematist would require in
