One specimen from Himantopus himantopus. 

 Küimandjaro-Meni: Natron Lakes. 



Meiioiioii titaii Piaget. 



Many specimens froni Pelecanus roseus. Some of tliese specimens, niales, fenia- 

 les and young, were taken from the inside of the host's poucli, wliere they sat very 

 strongly fixed at the skin. This African form should really be described as a variety 

 of iitan, differing noticeably by lack of complete transverse black-brown bars on the 

 abdominal segments, these bars being broken into lateral and median portions.

MeiioiKdi culiisiiis 11, sp. 



(PI. 7. fig. 11.) 



One specimen from Phalacrocorax africanus. 



Male, bod,v lengtli Lös mm., width O.tö mm., robust, hairy, abdoinen mostly 

 covered by the small transversal brown bands. He ad, length 0.4 mm., width O.w mm.; 

 half again as wide as long; front flatly rounded, temples with several conspicuous 

 long hairs; six long hair-s along occipital margin; no strong head markings. Pro- 

 thorax large with conspicuous long hairs in produced lateral angles and all along 

 rounding posterior margin. Metathorax with numerous 'strong hairs along straight 

 posterior margin; no strong markings any where on thorax. Abdomen short and 

 broadly elliptical, with very long hairs from postero-lateral angles of segments and a 

 transverse row of closely set shorter hairs along posterior margin of each segment; 

 also numerous still shorter hairs scattered irregularly over dorsum of segments 4 to 

 8 more abundant on the niore posterior segments; bi'oad pale-brown transverse bands

Meiiopon biicerotis n. sp. 



(PI. 7. tig. 12.) 



Many specimens, males and females, from the hornbill Bycanisles crislalus. 

 Only one Menopon has been heretofore recorded from the hornbills, viz., M. forci- 

 patum, figured but not described by Giebel. This african species is quite distinct 

 from the figures given by Giebel of male and female jorcipatum. Is a Menopon of 

 unusual form and general appearance. 



Male, length 2 mm., width 0.8 mm.; abdomen with crenulated lateral margins, 

 last two abdominal segments mucli narrower than preceding ones, head short and 

 wide with narrow angulated laterally projecting temples. Head, length O.sa mm., 

 width 0.6Ö mm., thus being twice as wide as long; front with longish, spinous hairs 

 and temples and occipital margin with numerous very long conspicuous hairs giving 

 the whole head an unusual spiny and hairy appearance; the ocular emarginations are 

 fairly distinct thus making it difficult to refer this species with certainly to Menopon ; 

 it might perhaps with equal right have been referred to Colpocephalum ; the temples
