1923.| H. C. Ropinson & C. B. Kioss: Notes. 359 
221. Oberholser has separated a male nightjar from East Sumatra -from 
C. concretus on account of the outer tail feathers being entirely without 
white or buffy tips or subterminal bands (C. mirificus Oberh., Smithsonian 
Misc. Collections, Vol. 60, No. 7, 1912, p. 7). Toone of three Bornean males 
in our possession the description of C. mivificus exactly applies. It seems 
evident, therefore, that the proposed form is based ona phase and has no 
existence in fact. 
p. $334. For APIDAE read MICROPODIDAE. 
223. For Apus read Micropus. 
224. Read Micropus affinis subfurcatus. 
226. For giganteus read gigantea. 
251. Collocalia linchi cyanoptila. We have recorded under this 
name specimens we have examined from Deli, N. E, Sumatra (Journ.. Straits 
Branch Roy. Asiat. Soc. 80, 1919, p. go): they are, however, small and are 
possibly more nearly allied to C. /. affinis Beavan, of the Andaman and 
Nicobar Islands. 
232. Collocalia linchi oberholseri. An individual from the 
Padang Highlands appears to belong to this form which is based on material 
from the Pagi Islands some 150 miles to the south. 
253 Collocalia linchi dodgei. Further consideration of specimens 
from Korinchi which we recorded as C. linchi (Journ. F. M.S. Mus. X, pt. 2, 
1918, p. 132) leads us to consider that they are the same as the North Bornean 
mountain race. 
252. Hartert (V6g. palaarkt. Fauna, p. 952) states that Cuculus 
micropterus micropterus Gould, visits in the Indo-Australian Archi- 
pelago in winter. It may therefore occur in Sumatra. 
254. An example of Cuculus optatus was obtained by Heer E. 
Jacobson at Fort de Kock in January, 1914. 
259. Penthoceryx sonnerati fasciolata. Muller's description 
covered birds from Java and Sumatra, but at the end he stated that the latter 
were darker—as is the case. We therefore accept Cuculus fasciolatus for the 
Sumatran race, confining Cuculus pravatus Horsf., to the Javanese bird. 
278. Chotorhea rafflesii. Stresemann has shown (Anz. Orn. Ges. 
Bayern, 1921, p. 24) that Bucco versicolor Raffles, is preoccupied by the same of 
P.S.L. Muller. Jesson’s Bucco Rafflesii is the first subsequent namie. 
285. Xantholaema haemacephala delica. Stresemann shows 
that Bucco Raffesius Boie, isa nomen nudum. (Anz. Orn. Ges, Bayern, 1921, 
p. 24) Parrot’s name is therefore available for the subspecifically distinct 
Sumatran bird. 
296. Dryobates canicapillus volzi Stresem., is possibly the 
same as lyngipicus c. suffusus Rob. and Kloss (Bull. Brit. Orn. Club, XL, 1919, 
p- 14. Selangor, South Malay Peninsula). We have no Sumatran birds but 
they appear to differ from canicapillus and auvantiiventris is the same way as 
does suffusus. 
301. Dinopium j. javanense Stresemann has recently separated 
Sumatran birds from those of Java as D. 7. palmaywmu in the belief that they are 
of smaller size (Arch. f. Naturgesch. 87, 1921, p. 43): we do not find this to be 
the case and have gone into the question elsewhere (Journ. Nat. Hist. Soc. 
Siam, V, pt. 2, 1923). Briefly we find that Sumatran birds attain a wing 
length of 139 mm. while the wings of Javanese reach 140 mm. with one excep- 
tion. The latter has a wing of 142.5 (fide Hesse, Mitt. Zool. Mus. VI, 1012, 
p. 190) and came from Temminck: though Hesse thought its Javanese origin 
not to be doubted it is quite possible that it is an example of D. j. intevmedia 
(Blyth). In any event 3.5 mm. in one specimen only in a bird of this size 
seems hardly enough to establish a local form as there are no other differences. 
314. The Zoological Museum at Bui:enzorg possesses a young example of 
Burylaimus j. javanicus from the Lampongs. This, the typical form, 
is probably confined to the southern extremity of the island.
