REPORT ON ZOOLOGY, MDCCCXLII : 
one new species, Scorpoena militaris, appears to have been added to the 
science. 
Dr. Richardson has also published, in the Ann. of Nat. Hist. ix. p. 15, 
120, 207, 384, and x. p. 25, contributions to the Ichthyology of Australia, 
and these are not yet concluded. The materials were furnished by Gould, 
whose assistant, Gilbert, had collected them at Port Essington, on the 
north coast of New Holland. Some remarks are added on some drawings 
of Fishes, made by Lieutenant Emery on the north-west coast of New 
Holland. There are also some observations on the species from Van 
Diemen’s Land and New Zealand, which are in the Museum at Haslar. 
Many species have been described as new, others are looked upon as 
species already known, and described anew in comparison with the 
descriptions already given by earlier and by more recent Ichthyologists. 
The new species are mentioned below. 
In Dieffenbach’s Travels in New Zealand, Lond. 1843, p. 206, Gray 
and Richardson have given a list of ninety-two species of new Zealand 
Fishes now knoAvn. Most of them are determined according to older 
authors, particularly Solander, Banks, and Forster. Some have also 
been collected by Dieffenbach, and are here described. Long articles 
are given on Hemerocetes acanthorhynchus, Cuv., Val. ; Hemiramphus 
marginatus, Lacep., and Rhombus plebejus, Soland. Three new species 
only have been described, viz. — Eleotris hasalis, Gray, Galaxias fas- 
ciatus, Gray, and Anguilla Dieffenbachii, Gray ; but they had already 
appeared in Gray’s Zool. Misc. p. 73. The notice of these Travels 
has been anticipated, although of 1843, from their close connection with 
Gray’s Miscellany. 
Camill. Ranzani has published four treatises on the New Fishes in the 
Bolognese Museum, in the ‘‘ Novi Commentarii Acad. Scient. Instituti 
Bonon tom. iv. 1840, p. 65 ; tom. v. 1842, p. 1, 307, and 339. Peculiar 
species and genera will be mentioned below. They are all figured. 
In the Annali Universal! di Medicina di Milano, August, 1841, is 
contained “ Developpement des Poissons : Memoire lu au Congres de 
Florence, par M. de Filippi.” (S. Rev. Zool. 1842, p. 45.) 
H. J. R. Jacobi de vesica aerea Piscium, cum Appendice de vesica 
aera cellulosa Erythrini ; Diss. Inaug. Berol. 1842. The author compares 
the varieties of the swimming-bladder, in all respects, especially as they 
are given in Cuvier and Valenciennes’ Nat. Hist, des Poissons. In an 
appendix, the swimming-bladder of Erythrinus, which is cellular in the 
anterior portion of the posterior division, is described, and a drawing of 
it is added.
