COLLOCALIA FRANCICA INEXPECTATA Hume 



Collocalia inexpedata Hume, Stray Feathers, vol. 1, p. 206, 1873 (Button Island, 

 Andamans) . 



Dr. W. L. Abbott collected two males on Pulo Tioman, October 12, 

 1900, and two males at Tanjong Silantei, east coast of Johore, July 26, 

 1901. 



This form occurs on the Nicobars, south Andamans, and in the 

 southern Malay States; once accidental in Tenasserim. 



The race is larger and has a darker rump than C.f. germani. 



COLLOCALIA LOWI ROBINSONI Stresemann 



Collocalia lowi rohinsoni Stresemann, Bull. Raffles Mus., no. 6, p. 98, 1931 (Pulo 

 Belitung, Southwest of Terutau Island, west coast Malay Peninsula). 



One female, Sichol, Bandon, May 17, 1930. 



This specimen does not exactly agree with the original description. 

 It does not have the bill larger or the feet stronger than in the single 

 female of C. innominata with which it has been compared. It differs 

 from that species, however, as follows: While the rump is lighter than 

 the back, it is darker, with the shaft lines less conspicuous than in 

 innominata; the shaft lines below less conspicuous and practically none 

 at all on the chest and throat; wing externally purplish black instead 

 of bluish black; inner margins of the remiges lighter; tarsi more heavily 

 feathered; wing longer, 135 mm. Outer tail feather, 56 mm; middle, 45 

 mm. This specimen may not belong here at all, but to an undescribed 

 form. If the specimen has been correctly determined, then the range 

 will be the Malay States northward through Peninsular Siam to Bandon. 



Robinson ®^ recorded it originally as Collocalia innominata and 

 states that it was found nesting in some numbers at the type locality 

 in December. 



COLLOCALIA INNOMINATA Hume 



Collocalia innominata Hume, Stray Feathers, vol. 1, p. 294, 1873 (Port Monat, 

 Andaman Islands). 



Dr. W. L. Abbott collected a single female at Lay Song Hong, 

 Trang, September 5, 1890. He gives the soft parts as: Iris blackish 

 brown; tarsus brownish flesh, claws black; bill black. Wing, 124 mm. 

 The tail is worn and cannot be measured accurately. 



Originally described from the Andamans, it has since been found to 

 occur from southern Tenasserim through Penmsular Siam to the Malay 

 States and (?) Sumatra. 



Deignan "^ took a pair on Doi Angka, 4,000 feet, April 20, 1931 ; this 

 is so far north of the loiown range that I beheve the specimens should 

 be carefully reexamined. De Schauensee ^* reports it from Chiengdao, 

 4,600 feet, January 16.
