In the Transactions of the London Zological Society Dr. Boulenger 
gives a second account of the rich fish fauna of Lake Tanganyika, 
from the collections of the Lemaire Expedition. A number of new 
genera and species of Cichlidz are described and well figured, three 
of the plates being in colors, the work of the artist of the expedition, 
M. Dardenne. 
In the Proceedings of the Scientific Society of Christiania Dr. Robert 
Collett discusses in detail the relations of Lycodes gracilis, a fish of 
the arctic parts of the Atlantic. Several figures are given, together 
with detailed description. Dr. Collett regards Z. perspicillum as 
probably the young of Z. reticulatus, L. rossi as probably the very 
young of Z. pallidus, and Z. zoarchus, from Nova Scotia, as certainly 
the young of Z. gracilis. These conclusions differ somewhat from 
those of Dr. Smith, noted a few months since. 
The species of filefish described by Jordan and McGregor from 
Clarion Island, Mexico, under the name of Cantherines carole, proves 
to be identical with the type of Cantherines, C. sandwichiensis Quay 
and Gaimard of Hawaii, a fact first pointed out by Mr. R. E. Snod- 
grass. It is not evident that either C. pud/us of the West Indies, or 
C. pardalis of the East Indies, is really different from C. sandwichiensis. 
In a private letter Professor D'Arcy W. Thompson, of University 
College, Dundee, corrects the current account of the genus Eumesog- 
rammus. ‘The type Æ. precisus has four lateral lines, not three, the 
fourth being a ventral branch, accessory to the third, and running 
from the breast to near the vent. This was correctly described by 
Dr. Reinhardt, but overlooked by later authors. 
In a recent note in the Watura/ist on Dr. Charles Wilson Greene's 
studies of the California toadfish, or “ midshipman ” (Porichthys nota- 
tus), the writer, by a slip of the pen, made a statement just the 
Opposite of the truth. 
The fish showed no luminosity, save when excited by electricity 
or by ammonia. In an aquarium made alkaline by ammonia water 
all the spots and organs of the lateral line gave out a brilliant glow, 
fading away in about twenty minutes. Parts of the fish, after death, 
were luminous under ammonia. A similar effect was shown by 
severe electric stimulations, but a mild current produced no effect.
