THE STATUS OF THE GENERIC NAME HEMIPROCNE 



NITZSCH. 



BY HARRY C. OBERHOLSER. 



The generic name Hemiprocne Nitzsch is commonly consid 

 ered to date from this author's "Pterylographie," 1840, pp. 31, 

 123, but it was first proposed eleven years before in an anatomi 

 cal paper usually overlooked (Observ. Av. Arter. Carot. Com., 

 1829, p. 15), in the main text and its accompanying footnote, 

 after the following fashion : 



"3. Macrochires (S. longimanae) in duas dividendae tribus, 

 quarum una continentur Trochili, altera Cypseli et Hemiprocnes 

 N. 7t ) genera. Hae aves itidem dextra arteria carot. communi 

 semper carere videntur." 



" h ) Hemiprocnes genus, cui Cypselos, qui ill. TEMMINCKIO 

 longipennis, comatus, fuciphagus, torquatus vocantur, aliosque 

 accensio, a veris discrepant Cypselis et hallice sive digito pedum 

 primo retrorsum semper verso, et digito rum phalangum numero 

 eodem, qui in ceteris avibus solemnis est." 



Although in this place, as will be noticed, the word occurs in 

 the nominative plural to conform to the Latin construction of 

 the sentence, the author's intent is clear, particularly in light 

 of his use of the name in the singular form Hemiprocne a few 

 years afterward in his " Pterylographia Avium, pars prior," 

 1833, page 21, though here without diagnosis or mention of 

 any species, and still later (Pterylographie, 1840, pp. 31, 123) 

 when he gives a formal diagnosis and includes the species 

 Hirundo zonaris Shaw and Hirundo acuta Wied (=Chaetura 

 cinereiventris Sclater) . 



Meanwhile, however, a little-known author in a forgotten 

 book (Riemann , Zoolog. -technol . Leitfaden f tir Realschulen und
