NOVITATES ZOOLOGICAE XXV. 191 S. 351 



adopted Bonaparte's name pijliriopsis * for the typical T. calva calm, while he 

 thought that the northern form, which Reichenow named sharpei, was true 

 calva, a quite impossible course, as the southern bird is the true calva and 

 pytiriopsis is merely said to difier from delalandei by smaller size (!), and no 

 exact locality given ; Jardine's figure (very bad, like all illustrations in Jardine 

 and Selby's work) is quoted by Bonaparte, but it is not exact enough for any 

 conclusion, and has not either a definite locality. 



T. calva sharpei differs from T. c. calva by having the head brighter and 

 slightly more yellow, the nuchal collar better defined and clearer grey, wing 

 (cJ?) 148-162 mm. Thisv form inhabits Western Africa from Sierra Leone 

 (Clark, Bower, Kelsall, Kemp) to the Lower Niger (Felix Roth, Ansorge, Braham) 

 and Kalabar (Ansorge and Brit. Mus.). 



5. Treron calva salvadorii (Dubois). 



" Vinago salvadorii, subsp. nov." Dubois, Proc. Zool. Soc. London, 1897. p. 784 (" Afrique tropi- 

 cale orientale et centrale "—terra typica Tanganyka, as the author only e.xamlned Tanganyka 

 speciineas, no doubt from the western shores, though no esact locality has been stated). 



Lilie all the foregoing subspecies with the bare portion of the forehead 

 longer than the rhamphotheca, but the nuchal collar very sharply defined and 

 brighter blue-grey or lavender-grey, greenish colour brighter and more yellowish 

 above and below, especially on the crown and neck. Wings 3 167-179, $ 157- 

 167 mm. 



African lake districts from the western shore of Lake Tanganyka to Uganda, 

 Kavirondo, Unyoro, and Mt. Elgon. In the Trmg Museum from the following 

 localities : Russisi River between Lakes Kivu and Tanganyka (R. Grauer), 

 Marienseen (R. Grauer), Ussuwi, between Ussuwi and Lake Urigi, Lake Urigi 

 (Rud. Grauer), Kwidgwi Island in Lake Kivu (R. Grauer), Rutshuru plain, 

 1,600 m., between Albert Edward and Kivu (R. Grauer), Entebbe (F. J. Jack- 

 son, R. Grauer, L. M. Seth-Smith), Ngongo in Usoga (W. J. Ansorge), Unyoro 

 (R. Grauer), Kavu'ondo (W. J. Ansorge), Mpanga Forest in Toru (R. Grauer) ; 

 Mt. Elgon (British Museum). The Mpanga Forest and Kavirondo birds, as 

 well as the Unyoro specimens from Grauer, agree well with qther salvadorii, while 

 the bird from Kichuchu in Toru (see above, under uellensis) is much darker, like 

 true calva, and appears to have the nuchal collar more mdistnict, but, bemg 

 worn and dirty, this cannot well be seen ; a female from Fadjao is less bright 

 and has the collar less distinct than salvadorii, and is almost sure to belong to 

 uellensis. 



Two specimens, marked <J and ?, shot by Grauer, in " the forest west of 

 Tanganyka" at 1,900 and 2,000 m., the same day (13. vi. 1908), are puzzling. 

 The female, from 1,900 m., has the collar more indistinct, head darker, and 

 agrees perfectly with specimens shot 340 km. ^^est of Baraka and at Kindu, at 

 elevations from 400 to 1,200 m., while the male, from 2,000 m., is brighter, and 

 agrees better with salvadorii, though the head is not quite as bright as in most 

 salvadorii. 



* Reiohenow's quoting " Vinago pyterioptia" Verreaux, Rev. et. Mag. 1851. p. 421, is a slip, 

 as the name occurs nowhere in that work.
