(Figures 208 to 211) 



The exact statxis of this form is imcertain. Since first 

 mentioned from French Somaliland (Hoogstraal 1953D), a small 

 amoxint of additional material, all from camels in the Somali 

 biotope, from British Somaliland and Gebel Elba of southeastern 

 Egypt, has been seen. An attempt will be made to obtain living 

 material for rearing studies in order to define the morphological 

 characters and taxonomic position of this form, both sexes of 

 which resemble extreme variations among other species. The con- 

 sistency with which males and females of this form are found to- 

 gether throughout coastal eastern Africa north of the equator 

 arouses suspicion that this is a distinct genetic entity. 



The male subanal shields lie directly posterior of the cen- 

 tral axis of the adanal shields; the scutum has ©iaaracters in 

 common both with heavily pionctate H. marginatiim and H. impeltatum . 

 The female scutum is also similar "^o that of both of these species 

 but the genital apron is like that of K. dromedarii although more 

 depressed posteriorly. The outline of^this apron in the specimen 

 illustrated (Figure 211 ) represents the maximum width of this 

 structure observed among available material; in other specimens 

 it is more narrowly and elongately triangtilar, as in H« drome - 

 darii . The apron is not flanked by two lobes as in hT impeltatum , 

 and its profile differs greatly from that of H. impeTtatum .
