Show 742 MR. E.WARD ON A NEW BIRD OF PARADISE. [Nov. 18, wording of his communication. Mr. Coughtrey has since left Liverpool for N e w Zealand, whence, in due time, I hope to receive from him further entozoal contributions. The nematode from the larynx was probably an example of Ascaris osculata; but the Hsematozoa from the heart are, I believe, new to science. I have named the species as above, the specific title chosen having reference to the blunted extremity of the tail. In brief, the characters may therefore stand as follows :-Body of nearly uniform thickness, narrowing slowly in front and behind ; head simple in both sexes, semicircular in profile ; tail of the female straight, rather suddenly narrowing to a fine rounded point; tail of the male spirally curved, furnished with two unequal spicules, blunt at the tip, where it forms a small knob. Length of the female 6 inches ; male, up to 4 inches. In addition to the above diagnosis, I may add that the head of the female suddenly curves forward from a point where it measures about -g-V inch transversely, whilst the tail, at a corresponding distance from the extremity, does not exceed the y-i-jy inch in diameter. The knob-like projection at the end of the tail of the male measures only _ i F inch in breadth. As usual, in similar cases, I found the uterine ducts crowded with ova in various degrees of development, all of the most advanced embryos being included in a delicate chorional envelope. The position of the vulva could not be made out; but the embryos (figs. 12 & 13) were taken from the oviduct at a distance of one inch from the head. The long diameter of the ova gave an average of J}-Q inch, the embryos having a length of -fa inch, or thereabout, the greatest breadth scarcely exceeding that of the human red blood-corpuscle.

[Eeceived October 18, 1873.] About the end of September last I received from Singapore a collection of New-Guinea birds, amongst which there was a skin of a new species of the Paradiseine group.
