350 THE ZOOLOGIST. 
Mr. D. Sharp sent a communication “On the species of the genus 
Euchroma,” having reference to the two known species belonging to that 
genus of the Buprestidae. 
Mr. J. W. Douglas communicated “Observations on the species of 
the Homopterous genus Orthezia, with a description of a new species” 
(O. Normani). 
Mr. A. G. Butler communicated a further paper “ On the Lepidoptera 
of the Amazons collected by Dr. James W. H. Trail during the years 1873 
to 1875,” Part IV. Geometrites. This part of the collection consists of 
eighty-two species, thirty of which prove new to Science. 
Prof. Westwood communicated “ Notes on larva of Nycteribia,” by Baron 
R. Osten-Sacken. 
Mr. W. F. Kirby read ‘Notes on new or interesting species of

NOTICES OF NEW BOOKS. 
The Norwegian North Atlantic Expedition, 1876-78: Zoology— 
Fishes. By Roperr Cotterr. Large 4to, pp. 164, with five 
plates, three woodcuts, and map. Christiana: Grondahl 
and Son. 
In this handsome quarto volume, with most carefully executed 
lithographs, we have a section of the General Report on the 
Zoological Results of the Expedition organised by the Norwegian 
Government for the Scientific Exploration of the North Atlantic. 
This Expedition made three voyages in the years 1876, 1877 and 
1878, and several preliminary memoirs have been published in 
various scientific Journals, dealing briefly with the chief results 
obtained in different branches of scientific research. Two of these 
papers, by Mr. Collett, relating to the Deep-sea Fishes collected on 
the Expedition, were published in 1878, but without illustrations. 
Having been carefully revised and considerably expanded, they 
are now embodied in the more important quarto before us. 
During the first two voyages of 1876 and 1877, the number of 
fishes obtained was comparatively small, while the additions made 
to our knowledge of invertebrate forms were both numerous and 
important. The small number of fishes collected was believed to 
be due to the unsuitable nature of the dredging-apparatus at first 
employed, as well as to the fact that, in 1876, the investigations 
were carried on almost exclusively at great depths in the cold
