 the under parte small and less distinct on the belly, 



Measurements. Adult (twelve specimens) wing, 93.0-99.5 

 (96.7); tail, 70.0 79.5 (74.9); tarsus, L9.5 21.5 (20.7); culmen from 

 base of forehead, 27.0 30.5 (29.0). 



Range. Guiana, eastern Venezuela (Orinoco Valley), northern 

 Brazil (Rio Negro, Rio Branco). 



SPECIMENS EXAMINED. — Dutch Guiana: Vicinity of Paramaribo, 

 13; "Surinam" (Cragin), 1. British Guiana: Aunai (Whitely), 1. 

 Total, L5. 



Remabeb. Unfortunately we have not seen specimens from the 

 type-locality, Cayenne, but we assume that Surinam birds are suffi- 

 ciently close for purposes of comparison. Menegaux and Hellmayr 

 (Mem. Soc. hist. nat. Autun, 1906, 19, p. 109) give measurements of a 

 male and female from Cayenne which are slightly larger than the birds 

 from Surinam listed by them and those examined by us. The differ- 

 ence, however, is very slight and probably would not prove to be 

 constant in larger series. 



A male (Penard collection) from Aunai, British Guiana, collected 

 by Henry Whitely, 14 March, 1890 (or 1891), is very rufous, and re- 

 sembles specimens from Bahia, but in this case we think the rufous 

 tone is due to fading and not to individual or seasonal variation. 

 Specimens taken near Paramaribo in March do not differ in shade 

 from others taken in January, February, April, May, June, or Decem- 

 ber, all having the dark olive tone. On the other hand, a very old 

 specimen (M. C. Z. 84,580) collected by Cragin in Surinam, has not 

 faded appreciably and agrees very well with more recently collected 

 specimens from the same locality. 



2. Dendroplex picus altirostris (Leotaud). 

 Dcndrocolaptcs altirostris Leotaud, Ois. Trin., 1866, p. 166 (Trinidad). 



Type — M. C. Z. 77,156, Lafr. coll. 2,279. Adult 9 . 



Si bspecific characters. — Similar to Dendroplex picus picus Gmelin, but 

 slightly larger; spots on under parts larger and more distinct, especially on the 

 belly; hill very much larger, thicker, and heavier; culmen more curved. 



Measurements. — Type. Adult 9 — wing, 108.0; tail, &?).l>; 

 tarsus, 21.5; culmen from base of forehead, 32.5.
