248 MR. A. E. SHIPLEY ON EnTO-PARASITES. [Apr. 18, 



The skin of the body generally is covered with numerous 

 brown blotches, separated by i-ather sharp outlines from the 

 broad white reticulum. The centres of the blotches are i-ather 

 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 tiace of the large white patch lound the fi-ont 

 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 Kerdofan 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 lace of 

 Nigeiian Giraffes, a i-ace closer to the Nubian Giraffe than to 

 any other form, but I do not think that as yet thei-e is com- 

 plete 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.

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, howeve)-, kindly sent me by Dr. von 

 Linstow of Gottingen. The South- American parasites I owe to 

 the kindness of Mr. Rosenberg, of Haverstock Hill.
