The Zandr (Lucio Perea Zandr). — Mr. Frank Buckland, writing* in Land 
and Water, states that lie has received a specimen of the German fish, the 
Lucio Perea Zandr.” The zandr is also known by the name of the ‘^Pike 
Perch.” In external appearance it resembles both the pike and the perch, 
the scales being particularly perch-like ; the weight of his fish was, when 
caught alive, 6^1bs. ; its length 24 inches. Herr Brockhardt, one of the 
principal purveyors of good things in Berlin, has stated that he shall be 
very glad to send him next spring a living zandr of 111b. or 121b. weight, 
and will also procure young zandr and transmit to this country. Zandr of 
three to four inches long are to be had in February and March. It is, he 
believes, essentially a lake fish, and is not known to the west of the Elbe. 
Although it may be called a river fish, it appears to flourish only in the 
lake-like extensions of the Naffel, Spree, and other rivers of this part of 
North Germany. It is considered a great delicacy in Berlin. 
The Zoological Society. — The papers read before this active society 
during the past quarter have been both numerous and important. The 
following is a brief summary of some of the principal communications, 
given with a view of enabling our readers to see whether any work has 
been done on their particular subject : — Mr. Sclater read a paper on a collec- 
tion of birds from the Solomon Islands, which he had recently received 
through the courtesy of Mr. Gerard Krefft, Curator and Secretary of the 
Australian Museum, Sydney, N.S.W. The collection was stated to be one 
of great interest, embracing twenty-one species, three of which appeared to 
be previously undescribed. One of these, anew species of Grakle, was pro- 
posed to be called Gracula Krefti. In concluding his paper, Mr. Sclater 
made remarks upon the general character of the Fauna of the Solomon 
Islands, which were shown to belong zoologically to the Papuan or Austro- 
Malayan Sub-region of the Australian Begion. — Mr. Sclater also read the 
third part of a series of papers on the birds of the vicinity of Lima, Peru, 
with notes on their habits by Prof. W. Nation, C.M.Z.S., of Lima. — Dr. J. 
E. Gray communicated a memoir on the families and genera of Tortoises, 
Terrapins, and Turtles, and on the characters afforded by the study of the 
skulls of these reptiles. — Dr. J. Murie read a note on the sublingual aperture 
and sphincter of the gular pouch in the Great Bustard (Otis tarda), as 
observed in an adult example of this species which had recently died in the 
Society’s menagerie. — Dr. Murie read also a report on the skulls of the 
Eared Seals (Otaria) collected by Lecomte, the Society’s keeper, in the 
Falklands, which were shown to belong to two species, Otaria jubata and 
O. nigrescens. — Mr. W. H. Flower read a note on the substance ejected 
from the stomach of the male Wrinkled Hornbill (Bucet'os corrugatus) 
lately living in the Society’s Gardens, concerning which a communication 
had been made to the Society by Mr. Bartlett at a previous meeting. Mr. 
Flower stated that the envelope in which the ejected food was contained, 
consisted of the entire epithelial lining of the stomach of this bird. — A 
communication was read from Prof. Owen, F.B.S., ‘‘ On Dinornis,” forming 
the fourteenth part of his series of memoirs on this subject. The present 
paper related chiefly to the craniology of the genus j but contained also the 
description of a fossil cranium from the London clay of Sheppey, in the 
collection of the Earl of Enniskillen, F.R.S., which Prof. Owen considered
