dlspar, n. s. " Urom. supra nigro-fuscus (mas) aut cinereo-flavus (faem,); 

 " segmenta siibcaudalia squarais dentatis, in series plures dispositis." 

 These two species, the differences between which were first noticed by 

 Ehrenberg and Hemprich, are more nearly related to each other than to 

 the Urom. ornatus, which, however, in outward form closely resembles 

 the Urom. spinipes. 



From the preceding analysis it will have been seen how much of 

 important matter is already contained in this valuable work. From its 

 continuation we are therefore justified in anticipating still further additions 

 to our knowledge, of which we propose occasionally to avail ourselves 

 in this department. No portion of the Fishes or Insects, the collections 

 of which are noticed in the prospectus, have yet appeared. 



Elements ofJVatural History, adapted to the present state of the Science, 

 containing the Generic Characters of nearly the whole .Animal King- 

 dom, and Descriptions of the principal Species. By John Stark, 

 F. R. S. E., M. W. S., Sfc. With illustrative Engravings. 2 vols.

As an elementary work on Natural History at large, this production, 

 although not ill adapted to convey much general information, is deficient 

 in several important respects, and particularly in not supplying that essen- 

 tial requisite to the beginner, an explanation of the terms employed 

 in the science which he is about to study. But the Elements, if as such 

 we are to regard the general remarks on natural objects, whether 

 organic or inorganic, and on animals and vegetables, occupy a compara- 

 tively small proportion of these volumes, and can by no means be 

 considered as their most prominent feature. It is as a IVTanual of Zoology 

 that they will be purchased and read, and it is as such that they deserve 

 to be recommended to general use more strongly than any compilation of 

 the kind, either in our ovra or in any other language, with which we are 

 acquainted. Of compilations in general they have indeed most of the 

 defects, and, as in the mass of such works, many errors are retained in 

 them which might readily have been corrected by referring, if not to 

 specimens, at least to original authours. But there is a redeeming merit
