This curious creature was said to have been found alive in a pail 
of milk. 
Hab. India. 
Order CLADOCERA. 
2. DapHNIA NEwporTi. (Pl. LXXII. fig. 3.) 
Carapace-valves oval, terminating posteriorly in a rather long 
sharp spine directed a little backwards, and furnished on both sides 
with spines. The surface of the shell is reticulated and hirsute, being 
roughened all over with short spines. The margins of the carapace 
are beset with short spines also, the dorsal margin from the extremity 
to the base of the head, the ventral margin for nearly half its length. 
The head is very obtuse and rounded, terminating anteriorly in a 
short, sharp beak. The rami or inferior antenne are of considerable 
size, and the sete or filaments are finely plumose. The sixth seg- 
ment of the body of the animal has five or six projections from it, 
two or three of which are small and rough, with very minute spines. 
The first is the longest, being prolonged and curved upwards ; the se- 
cond is large and well-marked ; and between the last and the hooks 
in which this segment terminates, the edge is beset with numerous 
small spines, the inferior six or seven being much the largest. 
I have named this Daphnia after my late friend Mr. George New- 
port, to whom I am indebted for the specimens sent to me several 
years ago. 
Hab, India. 
4, DEScRIPTION OF SOME New Species or INTESTINAL WORMS 
(EnTozOA) IN THE COLLECTION OF THE British Museum. 
By W. Bairp, M.D., F.L.S. 
Order NEMATOIDEA. 
1. ASCARIS SALVINI. 
Head naked; the valves of the mouth very prominent. Body 
cylindrical, unequally attenuated at the two extremities, the tail being 
considerably more slender than the anterior extremity, which is ob- 
tuse. The body is of a ferruginous colour, and surrounded with very 
distinct strize ; strize strong, about half a line apart from each other. 
Length about 23 inches. The only specimen found is a female. 
This species differs from Ascaris infleza, to which it is nearly 
allied, by the head being more obtuse, and the anterior extremity 
altogether less attenuated; the striz are very much stronger and 
more distant from each other; the valves of the mouth are much 
more strongly developed and prominent. 
Hab. Found on the outside of the intestines of the Oreophasis 
derbianus of Guatemala. 
This rare bird formed part of the collection made in Guatemala by 
Mr. Salvin. I have, accordingly, dedicated this species of Ascaris 
to him.
