Revieics — Dr. Anton Frifsch — Fermian Fauna of Bohemia. 375 



" There are," writes Mr. H. P. Woodward, " one or two patches 

 of the Tertiary and Secondary formations left as ' outliers,' capping 

 some of the hills, as Mount Bahbage and the Outaway Hills ; also a 

 small patch near Mount Fitton, which is all that is left of what once 

 filled the basin here. The plains which flank the ranges to the 

 north, east, and west are of Secondary age, and consist of clays with 

 Tertiary table-hills of quartzite and gypseous marls." This country 

 seems to offer some opening prospect in the future to the miner ; 

 several copper-mines actually exist among the hills, and there seems 

 to be a fair supply of drinkable water, but whether sufficient for 

 mining purposes on any large scale seems doubtful.

IN some introductory remarks the author states that the second 

 volume will be largely devoted to Amphibians in which the teeth 

 show a labyrinthic structure. From the circumstance that these 

 remains are more disconnected, they are often determined with 

 difficulty. The teeth exhibit two principal types, first, that in which 

 the plication is simple and rather irregular ; and secondly, that 

 which has a typical labyrinthic structure. The characters of the 

 vertebral column are less easily classified ; and the vertebra are not 

 always ossified and preserved. Dr. Fritsch offers some critical 

 remarks on Cope's classification of vertebral characters, observing 

 that even in Arclmgosaurus the thoracic vertebras are rachitomous, 

 while the caudal vertebrEB are embolomerous ; so that the two groups 

 Bachitomi and Emholomeri appear to be founded on characters of 

 different parts of the same vertebral column. 



The volume opens with some account of the Dendrerpetontid^. 

 The Bohemian species of Dendrerpeton are all new, and are named 

 D. pyriticmn, D. foveolatum, and D. ? deprivatum. Dendrerpeton 

 pyriticum is known from skulls which are 53 mm. long, and 48 mm. 

 wide. The orbits are subcii'cular, nearly midway in the length of 

 the head, and separated from each other by more than an orbital 

 diameter. The foramen parietale is one millimetre long, and is in 

 the middle of the length of the parietal bones. I'he nares are not 

 shown. The bones of the upper surface of the skull are ornamented 

 with small pits and radiating grooves. The premaxillary bone 

 carries six rather long slender teeth, which are curved backward, 

 and are two and a half times as long as the base is broad. The base 

 has about 14 furrows. Tbe maxillary bone is half as long as the 

 skull, and carries from 17 to 20 teeth, which become smaller from 

 the front backward, so that the sixteenth is only half as long as the 

 first. The nasal bones are the longest median bones in the roof of 

 the skull. The processes which are analogous to occipital condyles, 

 the author regards as processes of the supra-occipital bones or 

 capable of being otherwise interpreted. 



On the palate, the large vomerine bones unite with the pre-
