There is little to distinguish D. caboti with certainty from D. oleagineus, except its 
smaller size, a character of slight value. The sides of the head in fully adult males 
are nearly uniformly dark, but in younger birds and in most females light lores and 
cheeks are usual, and therefore in this respect they resemble D. oleagineus. 
D. caboti was described by Malherbe from specimens supposed to have come from 
Colombia, and named after Dr. Cabot, the companion of Stephens during his travels in 
Yucatan. Dr. Cabot, however, does not seem to have met with the species in Yucatan, 
as no specimen was in his collection when Salvin examined it in 1874. 
Its distribution now has been traced over the lowlands of Guatemala on both sides of 
the main mountain-chain, and thence southwards to Costa Rica and the forests of the 
Cordillera of Tolé; but no Woodpecker of this group has been found on the Isthmus 
of Panama. In South America, from Colombia to Bolivia, D. fumigatus is the 
prevalent form. 
3. Dendrobates sanguinolentus.

Dendrobates sanguinolentus, Hargitt, Cat. Birds Brit. Mus. xviii. p. 346°. 
D. caboti similis, sed dorso toto medio coccineo suffuso, statura quoque paulo minor. Long. tota circa 6-0, ale 
3:15, caude 1°75. (Descr. maris ex 8. Domingo, Nicaragua. Mus. nostr.)

Richardson), Rio Escondido (Richmond). 
Mr. Sclater described this Woodpecker from a specimen obtained by Leyland at 
Omoa, in Honduras. This specimen is in the Derby Museum at Liverpool, and until 
recently has remained the only one known. About two years ago, Mr. Richardson 
secured several examples of a Woodpecker of this group at Santo Domingo, in the 
Province of Chontales, in Nicaragua. One of these is a male with the back richly 
suffused with dark red, and belongs doubtless to D. sanguinolentus ; the others are 
not so coloured, nor are two specimens from the Rio Escondido nearer the coast, which 
formed part of Mr. Richmond’s collection. They all, however, agree closely in dimen- 
sions, and undoubtedly belong to the same species. We have never seen the red 
colouring of the back on any specimen of D. caboti, and are thus driven to the 
conclusion that this peculiarity is characteristic of old males of D. sanguinolentus only 
and that younger males and females are not so adorned. 
Mr. Hargitt considers D. reichenbachi, Cab. & Heine, to belong probably to this 
species®. If this is correct, its range extends to Venezuela.
