No. 389.] REVIEWS OF RECENT LITERATURE. 437 
. this series, just published by Dr. Japetus Steenstrup and Dr. Lütken, 
treats of the development and structure of the “ Molidæ, or Head- 
fishes,” called by them “ Klumpfish,” or “ Moon-fish,” the family 
constituting the two genera Mola and Ranzania. 
The changes which take place in the growth of these fishes are 
most remarkable, and have led to the establishment of very many 
(thirteen) nominal genera, besides the two which have a real basis 
in adult structure. The most persistent of these genera was the 
diminutive Molacanthus, a stage of growth which was naturally and 
apparently logically taken for an adult fish. 
This paper, like all of Dr. Liitken’s, is very conscientiously written 
and admirably illustrated. 
We miss, however, the usual “ Résumé en français,” an important 
help to those whose knowledge of Danish is casual and incomplete.

Fishes of New South Wales. — The government of New South 
Wales has lately published a review of trawling operations of H. M. S. 
“ Thetis,” conducted along its coast by Frank Farnell. 
The record, valuable for economic purposes, is supplemented by a 
“ Scientific Report ” on the fishes by Edgar L. Waite. In this report 
numerous species are enumerated, two of them new to science, with 
fairly drawn figures by Mr. Waite. 
The nomenclature is very antiquated, the author apparently de- 
pending almost entirely on Giinther’s Catalogue of the Fishes of the 
British Museum, the one published volume of Boulenger’s masterly 
catalogue being ignored. There is reason to doubt the accuracy of 
certain identifications. The new species are as follows: Histiopterus 
farnelli, Chimera ogilbyi; but doubtless others will appear when the 
material has been more critically studied. D. S. J. 
Fresh-Water Ostracoda of South America. — The fresh-water 
collections made at Montevideo, in the Straits region, and in Chili by 
the Hamburg Expedition, have been examined for Ostracoda by Dr. 
W. Vavra? of the Prag Museum. He finds but eight species, three 
of them being well-known cosmopolites, while the remaining five are 
described as new. The list of Ostracoda known from South America 
is thereby increased to twenty-six. One species is added to the 
subgenus Chlamydotheca, a group characteristic of the southern
