Now Terpsiphone rufiventer somereni Chapin, 1948 . See Urban et al., 1997: 543 . HOLOTYPE : AMNH 652518 , adult male, collected at Budongo , ca. 01.47N , 31.35E ( Polhill, 1988: 21 ), Uganda , on 14 June 1919 , by V.G.L. van Someren. From the Rothschild Collection. COMMENTS : Chapin gave the AMNH number of the holotype in the original description and noted that he had studied 30 specimens , probably including the type but excluding immature and juvenile specimens; he had also borrowed some specimens from van Someren. It proved very difficult to decide which specimens are paratypes , as Chapin did not indicate this on the labels. All specimens of somereni from Budongo and Bugoma are paratypes : Budongo: AMNH 652513–652517 and 652519–652527; Bugoma: AMNH 652528–652533. There are also two paratypes from Budongo at RMCA ( Louette et al., 2002: 56 ). Chapin (1948: 121) presented a chart of the occurrence of hybrids in the Entebbe-Mabira area of Uganda where somereni also occurs. Using this chart and his description, I was able to decide that three additional males, five females , and three immatures were possible paratypes of somereni : Lugalambo: males, AMNH 652534 and 652535, females, AMNH 652536, 652537, and 6452538; Mabira: immature female, AMNH 652540, female, AMNH 652541; Mubango, female, AMNH 652542; Kyetuma, immature male, AMNH 652546; Sezibwa River, male, AMNH 652552, and immature female, AMNH 652553.
