488 MR. O. SALVIN ON THE AVIFAUNA 
rostro pallide corneo, pedibus nigris: long. tota 4:7, alee 2:7, caude 1:7, rostri a rictu 
0-65, tarsi 0:9. Hem. mari similis. 
Hab. Yndefatigable Island (Habel). 
Obs. Colore ab omnibus distincta, sed forsan avis haud adulta. Attamen mas et 
femina, specimina sola que nobis adsunt, vestitu omnino congruunt. 
“Found with the various species of Geospiza, and with them frequenting the sea- 
shore at low water. In the stomachs of the specimens collected I found insects, besides 
vegetable substances.”—//. 
Genus CAMARHYNCHUS. 
This genus, though stated by Mr. Gould to belong to the same group of Finches as 
Geospiza, differs considerably from that genus. It has, however, the same character- 
istically short tail and robust tarsi and feet; the coloration, too, is somewhat similar, 
except that instead of being in the adult male entirely black, the head and neck alone 
are black, the upper surface of the body being variegated and the under white or 
mottled. The chief point of difference between Camarhynchus and Geospiza lies in the 
form of the bill. The lower edge of the maxilla in Camarhynchus is not nearly so 
strongly angulated, but in some species is nearly straight and in others continuously 
curved. The bill, too, of the former is more compressed, being less tumid in the 
portion immediately anterior to the nostrils. 
As regards its bill Camarhynchus has perhaps its nearest ally in Meorhynchus, a genus 
represented by one species, V. nasesus, which is found on the west coast of Peru. But 
Neorhynchus has a still more robust bill, and the edges of the mandible strongly arched ; 
the tail, too, is of a length usual in Spermophila, and the feet of normal strength; in 
coloration Neorhynchus is decidedly Spermophiline.

? (Indefatigable Island) fusca, uropygio paulo dilutiore, alis et cauda obscurioribus, 
plumarum marginibus dorso concoloribus: subtus pallide ochrascenti-fusca: rostro 
flavido, pedibus nigricantibus: long. tota 4:5, ale 2°6, caudee 1:6, tarsi 0°85, rostri a 
rictu 0:5, 
Hab. James Island (Darwin); Indefatigable Island (Zabel). 
Obs. Of two specimens in the British Museum one appears to be a young male, being 
darker than the other on the upper plumage. Long. tota 4°6, ale 2°75, caude 1°6, 
tarsi 0°9, rostri a rictu 5:5. 
The other specimen is paler above, and is probably a female. 
Dr. Habel only obtained a single specimen of this species, of which he remarks :— 
“The habits of this species resemble those of the Geospize.”—H.
