CAMPTOSTOMA

(Tyrannidae; Ϯ Northern Beardless Tyrannulet C. imberbe) Gr. καμπτος kamptos  curved  < καμπτω kamptō  to bend; στομα stoma, στοματος stomatos  mouth; "Genus novum Tyrannidarum, Tyrannulo affine: rostrum altum, breve, valde compressum, apice acuta et dente finali nulla; culmine multum arcuato et regulariter incurvo, gonyde paulum ascendente; vibrissis rictalibus nullis: alæ modicæ, dimidium caudæ attingentes; primariis secunda, tertia et quarta inter se æqualibus et quintam paulo excedentibus, sexta his paulo breviore sed primam superante: cauda modica quadrata: tarsi breviusculi: pedes ut in genere Tyrannulo.    C. IMBERBE, sp. nov.   ...   There is no doubt about its belonging to the Tyrannidæ, but the form of the bill appears to be quite different from that of any bird hitherto recognized as of that family, and to require a new generic appellation. I have therefore called it Camptostoma from the arched form of the culmen. The specific name imberbe refers to the entire absence of rictal bristles. I consider Tyrannulus to be perhaps its nearest-allied generic form, from which, however, it may be at once distinguished by the peculiar depth and compression of the bill." (P. Sclater 1857); "Camptostoma Sclater, 1857, Proc. Zool. Soc. London, 25, p. 203. Type, by monotypy, Camptostoma imberbe Sclater." (Traylor in Peters 1979, VIII, 13).
