62 Genus Omithodoros 



Museum possesses numerous specimens of nymphs and adults collected 

 by the Challenger Expedition, 28, vm. 1876, at St Paul's Rocks from 

 birds' nests, where they were found together with small spiders, etc. 

 The specimens, preserved in spirit, were mostly yellowish or reddish 

 brown in colour. Neumann (xn. 1907, p. 193) records specimens found 

 on the ground at Cargados Carajos (Siren Island) by Mr J. Stanley 

 Gardiner.

ORNITHODOROS PAVIMENTOSUS Neumann, 1901. 



Figs. 90-92. 



Lit. and Icon. : Neumann, 1901, p. 257, Fig. 1, of legs I and II*.— Dbnitz, 1906, 

 pp. 144-148, PI., Figs. 2 and 3, of legs I and IV*. 



Male : Unknown. 



Female : Body short oval, rounded at both ends, 12x8 mm. ; 

 covered by contiguous, flat granulations (whence " pavimentosus "), 

 smaller on the depressed areas; coarse hairs, especially anteriorly. 

 In other respects like 0. savignyi, except that the protarsi and tarsi 

 of legs I, II and III are much shorter, with the dorsal protuberances 

 arranged close together (see Fig. 58 and compare with Figs. 70, 71). 



Neumann's description is based on a single dried 1 ? taken by 

 Schenk at Bethany, Great Namaland, S. Africa (Berlin Mus.). In his 

 original description, Neumann pointed out the differences in the leg 

 structure between this species and 0. savignyi (should be 0. moubata as 

 pointed out by DSnitz). According to Donitz, who has examined many 



1 This may account for the " black " eyes.
