ZOOLOGICAL LITERATURE. 
LOPHOBRANCHII. 
Phyllopteryx. Dr. Gunther has given a short account of the fishes of this 
genus, Proc. Zool. Soc. 1865, p. 327. He refers to it three species : 1. Syn^ 
gnathus foUatus (Shaw), of which a coloured figure is given on pi. 14. 
2. Haliichthys tceniophoras (Gray), o. Niyllopteryx eques, sp. n., from South 
Australia, pi. 15, in which the spines and seaweed-like appendages are 
developed in an extraordinary degree. 
Microphis bleekerij sp. n.. Day, Fish. Malabar, p. 266, from Cochin. 
GANOIDEI. 
Prof. Brandt is engaged in a monograph of the Sturgeons of 
Russia, and has read before the Academy of Sciences of St. 
Petersburgh a paper on the stages of development and classi- 
fication of Ganoids generally, with particular regard to the 
type of the sturionoid Antacm (from aviaKalos, Acipenser in 
Herodot.), an abstract of which is published in Bull. Ac. Sc. 
St. Pet. 1865, pp. 536-538. The results of the researches of 
the author are merely indicated, so that we defer an account 
of them until the actual publication of the memoir. 
I Acipenser sturio. Dr. Boll has recorded two instances of the occurrence 
of the Sturgeon in inland waters of Northern Germany, at a considerable 
distance from the sea. Arch. Ver. Freund. Ntrgesch. Mecklenb. 1864, 
p. 188. 
Lepidosteiis. Young specimens have the caudal fin placed entirely below 
the extremity of the vertebral column Sarchirus of Rafinesque). 
Agassiz, in Ann. Sc. Nat. 1865, iii. p. 57. 
Prof. Cope gives a descriptive synopsi| of eight species in^the Museum of 
^ the Academy of Philadelphia, of which Lepidosteus otariuSy L. crassus, and 
X. producius are new to science. Proc. Ac. Nat. Sc. Philad. 1865, p. 86. 
Dr. Alex. Smith has read before the B. Phys. Soc. Edinburgh an account 
of a new genus from Old Calabar, Herpetoichthys calaharicus, distinguished 
from Polypterus by the absence of ventral fins. Although this account has 
not yet been published, we mention it, because it has been reported in several 
non-scientific papers. 
ELASMOBRANCHII. 
Prof. Dumeril's work on this order has been mentioned 
above. The systematic arrangement being absolutely the same 
as that of Miiller and Henle, we need not enter into it. Tlie 
number of specific forms has been considerably increased since 
the year 1841, as the author is enabled to enumerate some 
320 species against 212 of Muller and Henle j besides, he 
describes eight Chimseras. However, the number of species 
described for the first time in this work amounts to six only, 
which will be mentioned below.
