Prof. A. C. Haddon from Torres Straits. Of these, three (Parapellene 
haddonii, Ascorhynchus tenuirostris and Rhopalorhynchus clavipes) are 
new. 
Hexapopa.—The last number of the Kansas University Quarterly 
(Vol. II, No. 3, 1894) contains “ New genera and species of Dolicho- 
podide,” by J. M. Aldrich, and “ Descriptions of North American 
Trypetide,” by W. A. Snow. 
Motuiusca.—The molluscs collected during the United States 
Expedition to West Africa, in 1889-90, have been made the subject of 
a report by Mr. R. E. C. Stearns. In all there are 122 species, birds-it 
uted as follows: Pelecypods, 35 ; Marine Gasteropods, 69; Land Gas- 
teropods, 82; Cephalopods, 5. (Proceeds. U. S. Natl. Mus. Vol. V, 
1893.) 
Cuorpata.—Balanoglossus has recently been found at Broken Bay 
and at Jervis Bay, New South Wales. The genus was previously 
unknown from Australia. 
Prof. W. E. Ritter describes a new Tornaria from California, the 
first indication of the existence of Balanoglossus on the Pacific coast 
of the United States. This Tornaria, like the Bahaman form, pos- 
sesses tentacles on the longitudinai ciliated bands, and like the form 
described by Metschnikoff has a second circular band of cilia. In the 
oldest Balanoglossus obtained by the transformation of the Tornariz, 
but two pairs of gill slits had appeared, and there is farther a thick- 
ened cesophageal band of epithelium which -Professor Ritter would 
compare, in function at least, with the endostyle of Tunicates and 
Leptocardii. Lastly, the nerve cord does not arise by delamination 
but by a sinking down of the whole ectodermal nerve layer in a man- 
ner somewhat like that in Amphioxus. In the stages studied there 
was no trace of neuropore or neural canal. 
An important collection of fresh water fishes from Borneo, examined 
by M. Leon Vaillant, extends the number of species now known from 
that Island to 322. M. Vaillant points out the strong resemblance of 
the fish fauna of Borneo to that of Indo-Malaysia. (Revue Sci., Feb., 
1894.) 
According to Mr. F. C. Test, the “ Gopher F rog,” Rana aesopus 
Cope, is subterranean in its habits, living in the burrows of the Gopher 
Turtle. It probably feeds on the insects living in the burrows, for 
holes ss a flourishing insect fauna, to a great extent peculiar 
tothem. (Science, 1893.)
