J GANOIDEL - 
Calamoichthys (J. A. Smith) is the new name for the new genus of Ganoid 
fish mentioned as Hcrpctoiclithys in the Zoolog. Kecord, ii. p. 208. It is 
described in Pfoc. E. Soc. Edinb. v. 1866-06, pp, 664-669, or in Ann. & Mag. 
Nat. Hist, xviii. pp. 112-1145 and more fully in Trans. E. Soc. Edinb. 1866, 
pp. 467-479, where figures on pis. 31 and 32 are added. Dr. Traquair has 
joined his notes on the anatomy of this fish to the publication in Ann. & Mag. 
I, c. ^an error in the paper is corrected in Ann. & Mag. N. H. xviii. p, 496). 
ELASMOBRANCHII. 
Prof. Gegenbaur has examined the heart of various Plagio- j 
stomata [Acanthias, HeterodontuSy Hexanchus) y and found that 
the valves of the hinder row differ anatomically and functionally 
from those known in Selachians. He distinguishes them as 
^ Gongue- valves from the others (pouch-valves). The foremost 
row of valves only is homologous to the valves at the ostium | 
arteriosum of Teleostei. The hulbus arteriosus of Ganoids, | 
Selachians, and Chimseras is a part of the heart morphologically i 
different from that of Teleosteous fishes. The former is a pro- i 
longed and in some respects independent division of the ventri- j 
cuius, which also in Teleosteous fishes is not entirely absent, but 
generally shorter, and without a plurality of rows of valves. ; 
This division is the conus arteriosus of higher Vertebrates. Jena. I

Messrs. Bocage and Capello have published a very complete 
account of the Sharks of Portugal, see p. 132. T^iey enumerate 
27 species, all of which are described. As the authors have 
already published descriptions of the species then regarded as 
new in Proc. Zool. Soc. 1864, pp, 260-263, which we mentioned 
in Zool. Record, i. p. 186, we have to add here only that 
coloured figures of them are given in this publication, with 
illustrations of their dentition, &c. 
Ccfutrophorus. Messrs. Bocage and Capello state that their C. lusitanicus . 
is identical with C. granulosus (M. & II.), and their C. crcpidalhus with C 
calccus (Lowe). L. c. p. 23.
