irom an Eland in the Zoological Gardens at Edinburgh. It is 

 interesting to include a description and figure of the Eland 

 Linognathus here for the purpose of comparison. 



Basal plate : This closely resembles the plate of L. pitkodes in 

 the bifid lower end, the median suture, and median raised strip. 

 Parameres : Proximally broad and fitting around the mesosome 

 closely, a feature in which they resemble those of L. limnotragi 

 '(which wrap in around the mesosome extensively) and L. pithodes, 

 in which there is a broad leaf-like shelf {see p. 264). They 

 resemble L. cavim-capensis in the possession on the inner concave 

 surface about halfway down of an area of thickened chitin, 

 longer than the so-called "nodule" in the Procavian Linognathus. 

 The appearance suggests, in both instances, a strengthening of 

 the middle part for clasping the mesosome. Mesosome : As in 

 L. pithodes, a pseudo-penis is present and fused with the rest of 

 the endoraeral chitinisation (text-fig. 6). A thin ledge of thin 

 •chitin runs along the outside of each of the two parallel bars. 

 Between them lies the aperture and what I interpret as the 

 i}rue penis.

Both Enderlein and Neumann (see 8, p. 44) have described 

 this isolated louse-form ; but Neumann's description is much 

 the fuller, and includes a figure and description of the male
