ments. The trachez are not nearly so regular as in the larva of 
Anthomyia ceparum, by the side of which I placed it; though the 
present larva scarcely appears to belong to the Muscidz, as there 
are minute antennz present, there being no trace of them in the 
muscid larve as a rule. 
As represented in the figure at 4, dorsal view, and d, lateral 
view, two main trachez end each in a large dorsal tubercle, each 
with a tuft of fine respiratory sete; the cleft ventral plate being 
fleshy at the tips. One of the respiratory tubercles is represented 
as seen from the side atc; it gives rise to a fan-like series of 
radiating fine setæ, which are directed upwards and a little for- 
wards towards the base of the tubercle. 
new species of mite was also received from New Jersey 
through Professor Verrill, which was found living in the sea. It 
may receive the name of Bdella marina (Fig. 2: A, upper; B, 
under view; C, enlarged view of the proboscis and 2d pair of 
cephalic appendages, the so-called maxillæ). 
The body is slender, pear-shaped ; it is apparently eyeless, and 
the legs are no longer than the body is broad. The proboscis 1$ 
long, conical; the maxille long and slender, acute; extending 
some distance beyond the end of the proboscis. The age 
palpi are 4-jointed; the basal a third longer than the two follow- 
ing ones taken together, while the 4th (and last) is a little shorter 
than the basal joint. (The right palpus is not correctly "e
