In certain lights ; averaging slightly smaller. Wing, 99 ; tail, 59.5 ; culmen, 

 16 ; tarsus, 21 ; middle-toe, 17.5 mm. 



Remarks. — The above species is founded upon 11 males, 8 females, and 3 

 Immatures, all taken at the type locality, March 4-16, 1917. For comparison 

 I only have three females of Laviprocorax viinor from Pendek and Tobea 

 Islands, Buton Strait. There appears to be little difference in the sexes the 

 female only being smaller and duller than the males. The series of Lam- 

 procorax montosa is quite uniform, the purplish sheen on the throat and 

 jugulum being faint and only seen in a favorable light and absent or nearly so 

 from the sides of the neck. 



In Lamprocorax minor the purplish sheen is much more pronounced on 

 the throat and jugulum and even extends to the side of the neck ; it is also ap- 

 parently larger. The type of Lamprocorax todayensis (a female) from Mount 

 Apo, Mindanao, I'esembles Lamprocorax montosa very much, but the feathers 

 of the throat and jugulum are more lanceolate and the purple sheen is still 

 fainter, almost lacking ; the wings are duller. I attach no importance to the 

 latter, as the series of L. montosa shows that as the plumage fades the 

 iridescent green of the wings disappears and they become brownish and the 

 backs steely. Lamprocorax todayensis and montosa are both mountain forms 

 derived from the same stock, probably Lamprocorax minor, but as the 

 latter appears to be even a later immigrant from the south into Celebes, 

 It is better to treat them all as species for the present imtil more is known 

 of their distribution and relationship. 



Since writing the above the United States National Museum has 

 acquired a specimen of Lamprocorax viinor from Sumba Island. 

 This has the purplish sheen on the throat and jugulum even more 

 extensive than in the specimens from south Celebes; in fact it ex- 

 tends clear around the hind-neck, forming a collar. 



The various series average as follows : 



Ten male, L. montosa 



Eight females, L. montosa 



Three females, L. minor, from S. Cele- 

 bes 



One female, L. minor, from Sumba 



One female, L. todayensis, the type.
