Pompilid wasp common in the same locality, that we may regard it 
as a true mimic. Dr. Williston, describing another Mydaid (Cerio- 
mydas fraudulentus) from Chapada, Brazil, remarks that it shows a 
remarkable mimicry of certain species of Conops, occurring in the 
same region. Is it not, perhaps, likely that both the Ceriomydas and 
the Conops mimic some Hymenopteron ? T., D. A. CocKERELL. 
Zodlogical Notes. — Mr. A. E. Shipley, of Cambridge, England, 
has a valuable paper on the species of the peculiar group of parasites, 
the Linguatulida, in the first number of Blanchard’s Archives de 
Parasitologie. 
In the first number of the thirty-second volume of the /enaische 
Zeitschrift are three papers dealing with the anatomy of the whales. 
Dr. Friedrich Jungklaus describes the stomach in the young and in 
some cases of the adult of six species of Cetacea. Among his con- 
clusions he finds a striking difference between the stomachs of the 
toothed and the whalebone whales, that of the toothed whales differ- 
ing far more from the normal mammalian whales than does that of 
the mystacoccetes. On the other hand, the resemblances between 
the two types are regarded as the result of convergence. Otto 
Miiller discusses the alterations which the respiratory organs have 
undergone in the adaptation of these animals for an aquatic life, some 
other aquatic mammals being introduced for comparison. Wilhelm 
Dandt discusses the urogenital apparatus of the Cetacea. He con- 
cludes that the great development of the kidneys is due to the watery 
nature of the food, since in the absence of sweat glands all water 
must be eliminated by the lungs and kidneys. The strongly marked 
lobulation of the kidneys is secondary, not primitive. In the foetus 
the penis is external, but it becomes internal during embryonic life. 
The accounts in these three papers go far towards supporting the 
thesis that the Cetacea is a group of polyphyletic origin, and their 
resemblances those of convergence.
