Show 2 4 8 MR. A. E. SHIPLEY ON ENTO-PARASITES. [ A p r . 1 8 , The skin of the body generally is covered with numerous brown blotches, separated by rather sharp outlines from the broad white reticulum. The centres of the blotches are rather darker, but they do not show the trefoil pattern observed by Mr. Lydekker in the bull. Nor do they show the white centres conspicuous in the blotches along the sides of the Nubian male figured by Mr. Lydekker (P. Z. S. 1904, vol. i. pi. ix.). The general resemblance of the Nigerian female to the Nubian form is rather more striking than Mr. Lydekker found in the case of the male. There is no trace of the large white patch round the front of the neck where it joins the head, looking as if a white muffler had been tied round the neck and the ears, which forms so conspicuous a character in the Kordofan Giraffes (G. c. antiquorum) now exhibited in the Society's Collection. I am inclined to think that the evidence afforded by this young female strengthens belief in the existence of a distinct race of Nigerian Giraffes, a race closer to the Nubian Giraffe than to any other forqp, but I do not think that as yet there is complete evidence for identifying this female Giraffe and Captain Gosling's bull with the G. c. peralta of Thomas. It is certainly important that all examples of which exact localities are known should be carefully compared with other forms. 3. Notes on Ento-Parasites from the Zoological Gardens, London, and elsewhere. By A. E. S h tp le y , M .A ., F.R.S., Fellow and Tutor of Christ's College, Cambridge, and University Lecturer in the Morphology of the In vertebrata. [Received February 27, 1905.j (Text-figure 52.) The collections on which the following notes were made came chiefly from the animals in the Society's Gardens. The new species of Porocephalus was, however, kindly sent me by Dr. von Linstow of Gottingen. The South-American parasites I owe to the kindness of Mr. Rosenberg, of Haverstock'Hill. TREMATODA.
