New Perichsetidae.* — Dr. D. Rosa describes from Sig. L. Fea’s col- 
lection of Periclimtidre from Burmah a number of new species, viz. Peri- 
chseta carinensis , P. Bournei , P. Peguana, P. campanulata , Perionyx 
arboricola. 
New Earthworm from Ireland, f — The Rev. H. Friend describes a 
new earthworm from Dublin, which he calls Allolobophora hibernica ; 
when extended it is about 50 mm. long, and, in colour, most closely 
resembles A. mucosa , but the setae are in eight distinct rows. Mr. Friend 
learns from Dr. Rosa, of Turin, that he has lately found the same species 
in Italy. 
New Oligochaete.f — Mr. E. S. Goodrich describes a new Tubificid 
which he found on the seashore at Weymouth last August. To the 
naked eye it is quite indistinguishable from Heterochseta costata ; the 
whole surface of the body is clothed with a dense covering of fine 
“ hairs ” or “ bristles,” which are probably sensory. The blood is 
crimson, and a large number of round corpuscles float in the coelomic 
fluid. The most remarkable characters are exhibited by the genital 
system. On the anterior wall of the tenth segment are situated the 
paired testes, and in this segment the two funnels of the sperm-ducts 
open. These ducts are short convoluted tubes with thick glandular 
walls for the greater part of their course ; they open into a median 
atrium, which appears to be formed by an invagination of the epidermis, 
and is of considerable size. The ovaries are found on the anterior wall 
of the eleventh segment, and their ducts are short tubes, which open on 
the twelfth segment. On the tenth segment there are two pear-shaped 
spermathecse. 
The author proposes to name this worm, of which he hopes to shortly 
give a detailed account, Vermiculus pilosus, justifying the formation of a 
new genus on the possession of median male and spermathecal pores, 
and a covering of fine “ bristles.” 
New Naidomorpha.§ — Dr. C. Floericke has a few preliminary notes 
on what seem to be new species or varieties of Naidomorpha : — A species 
of Nais which is midway between N. elinguis Mull, and N. barbata Mull. ; 
a species of Ophidonais differing from 0. serpentina Oerst. in its smaller 
size and unswollen setae; three species of a subgenus, intermediate 
between Stylaria and Pristina. 
Glossiphonia tesselata in Chili. ||— Dr. R. Blanchard states that he 
received a small leech said to have been found on a specimen of 
Myotopamus Coypu mortally wounded in the “ Lagune de Cauquenes.” 
He was astonished to find that it was the well-known leech of Northern 
Europe, first described by 0. F. Muller. Four means are suggested by 
which the creature may have reached South America ; it might have 
passed to North America on some Palmiped, or by Calidris or Tringa , or 
it may have been transported by some domestic animal, or it may have 
come with damp earth surrounding plants. No one of these suggestions 
is, in Dr. Blanchard’s opinion, improbable.
