NEW SPECIES OF POPILLIA. 365 



1 ; Monochirus, 1 ; Echiodon 1, (a new genus recently de- 

 scribed by Mr. Thompson, in the Transactions of the Zoolo- 

 gical Society) , Syngnathus, 1 ; Acipenser, 1 ; Echinorhinus, 

 1 ; Zygmia, 1 ; Rata, 2, (one from vol. ii. of the Mag. Nat. 

 Hist. n. s. described by Mr. Couch). 



Besides the history of the new Fshes, the supplement con- 

 tains some valuable additional matter relating to species 

 which were figured in the previous volumes. The most im- 

 portant article of this description is one upon the growth of 

 Salmon in fresh water. This has been separately published 

 in the form of a large brochure, and is illustrated with six 

 admirably coloured engravings on steel, exhibiting the cha- 

 racter and natural size of the fish, and its exact appearance 

 at various stages during the first two years. One novelty in 

 the supplement with which we are highly gratified, is thus 

 spoken of in the preface : — 



" To render the pictorial part of this Supplement as useful as its size 

 and character would admit, I have introduced, as vignettes, representations 

 of the bones of the cranium of several well-known fishes, derived from the 

 works of Cuvier, Rosentha.ll, and others : and should this part of the plan 

 be approved as a worthy mode of occupying a portion of that space usually 

 devoted to lighter subjects, it may, on some future occasion be so enlarged 

 upon as to include an illustration of one cranium in almost all the princi- 

 pal genera. In the present instance, however, not to interfere with the 

 ornamental appearance of these crania, as vignettes, by a repetition of let- 

 ters or numbers in reference to each particular bone, I have confined the 

 markings to the Perch only, as here introduced, premising, that a little 

 useful perseverance will lead to a knowledge of the analogous bones in 

 other crania." 



We have only to add, that in the execution of the cuts, and 

 the general style of getting up, this volume is on a par with 

 any one in the series of Mr. Van Voorst's publications. 



SHORT COMMUNICATIONS. 



Descriptions of New Popillice, fyc. — Mr. Solly having obli- 

 gingly placed in my hands some specimens of the genus Po- 

 pillia, which he has received from the East Indies, I hasten 

 to transmit to you for publication descriptions of those species 

 which appear to be new.
