adult——W. L. Sclater describes (Proc. Zool. Soc., 1886) a fifth 
species of deep-sea coral of the genus Stephanotrochus. It comes 
from the British seas and was dredged at a depth of 570 fathoms. 
Some notes are given of its anatomy. 
Vermes. —Mr. W. B. Benham (Quart. Jour. Mic. Soc.) first gives 
a condensed historical review of the various works on earthworms, 
and a chronological record of the discovery of new facts; then 
briefly enumerates and describes all known earthworms; then 
takes the various organs in order, and points out their variations, 
and lastly describes some new species. Among these is Micro- 
cheta rappi from South Africa, a worm three feet six inches long, 
and therefore comparable with Antzus and Titanus from South 
America. Another species of Microchzta from Natal follows, and 
IS succeeded by Urobenus (1 sp.), Diachzta (1 sp.), and Trigaster 
(I sp.) all new genera. Mr. Weldon contributes to the same 
journal an account of Dinophilus gigas, found at Penzance, En- 
gland. Three species of the genus were previously known. 
Dinophilus is stated on the one hand to be related to the Arch- 
annelids, while on the other it retains many features characteristic 
of the common ancestor of these groups, in which Mr. Weldon 
includes Crustacea, Mollusca and Rotifera, as well as Chztopoda 
and Gephyrea. The relations of the body cavity, excretory system 
and pharynx point to a Turbellarian origin. The tapeworm, 
Tenta Jilrcollis, has been known as a parasite of the sticklebacks 
(Gasterosteus). Dr. Leidy now reports it from specimens of Amia 
North Carolina, though there is some doubt as to whether it 
Was really parasitic in these fishes.——-E. A. Rau reports four cases 
of trichinosis at Bethlehem, Pa., in the early part of the present 
year, two of which resulted fatally. All were caused by eating 
from the same infected pork. Kennel, in the last “Heft” of 
Semper’s Arbeiten,” completes his account of the development 
of Peripatus. He differs greatly on many points from Sedgwick’s 
account of the embryology of the species of the same genus from 
the Cape of Good Hope.
