432 ZOOLOGY. 
Journal of Science” the occurrence of the following recent addi- — 
tions to the American fauna, in depths of from 200 to 220 fathoms; 
of sponges, Trichostemma hemisphericum M. Sars, and Cladorhiza 
abyssicola M. Sars, with Hyalonema longissimum ; of echinoderms, 
Ophioscolex glacialis; of polyzoa, Flustra abyssicola G. O. Sars, 
and Escharella palmata Sars; of shells, Portlandia lucida, Pa 
frigida, Cylichna umbilicata and Cerithiopsis costulata ; of crus- 
tacea, Calocaris MacAndree Bell, Munidopsis curvirostra, a new 
genus and species, allied to Munida; Pseudomma roseum G. 0. 
Sars, Halirages fulvocinetus Boeck, Munnopsis typica Sars, and | 
several other species. Numerous interesting species, many ie 
them new to the American coast, were also dredged in shallower 
water, on the Orphan and Bradelle Banks, and at the entrance of — 
Gaspé Bay. Among the crustacea from these localities were 
Leucon nasicus Kroyer, Acanthostephia Malmgreni Bock, Ædiceros 
lynceus, and Aceros phyllonyx Boeck.

Tue Mouru Parts or rae Dracos Fry.—An important article — 
on the mouth parts of the dragon fly, Perlæ and allied forms (Or- 
thoptera amphibiotica), is published by Dr. Gerstaecker, in the i 
memorial volume of the Centennial Celebration of the Society of a 
the Friends of Science in Berlin, 1873. The author describes and 
figures the palpi of the dragon flies. They possess 4 one-joint e 
maxillary palpus, and 2-jointed labial palpus, which are not how: a 
ever in the maxillæ palpiform, but constitute a simple lobe (gales ' 
of Burmeister, Erichson and Ratzburg). In Hagen’s “Sy nopsisof = 
Neuroptera of North America” (1861) it is stated «mouth mine 
furnished with palpi.” This statement, which is morphologically 
inexact, was copied in the “Guide to the Study of Insects.” w 
will be corrected in the fifth edition of the latter, as it was UN 
tunately too late to correct the statement in the fourth editio 
now passing through the press, except in a few words in the pr 
face.—A. S. P o 
A New Tyre or Snaxes.—I have recently described 4 ere : 
from the Amazonian region of Peru, in which the spines a ie 
dorsal vertebra are so dilated at the summit as to present & S% 
of bony plates along the middle line of the back, homo% 
with the central pieces of the shield of a tortoise. The § 
presented other peculiarities and was called Genhosteus
