68 Oberholsei Status of Generic Name Hemiprocne Nitzsch. 



Gymnasien, 1838, p. 34) made use of the name as follows, for 

 which quotation I am indebted to Dr. Charles W. Richmond: 

 "Hemiprocne. Salange. Die vorigen Gattung ahnlich, aber 

 mit gewohnlicher Gliederung und Richtung der Zehen. H. es- 

 culenta, die indianische Schwalbe." 



By taking the term Hemiprocne from Nitzsch, 1840, the type 

 has been fixed as Hirundo zonaris Shaw; but this disposition of 

 the name can not stand, as may readily be seen by the above 

 references. If the earlier (1829) Nitzsch diagnosis be ignored, 

 the name will date from Riemann, 1838, and must displace 

 Collocalia ; but there is no sufficient reason for rejecting Hemi 

 procne as proposed by Nitzsch in 1829 (loc. cit.) since it was 

 then properly introduced into nomenclature. The species orig 

 inally included are now called Macropteryx longipennis, Macrop- 

 teryx comatus, Collocalia. faciphaga, and probably Hemiprocne 

 zonaris, respectively. The last appears as li torquatus," a name 

 apparently to be referred to the present Hemiprocne zonaris, but 

 here a nomen nudum and therefore not to be used in this con 

 nection. Of the three others, the first one mentioned, Hirundo 

 longipennis of Rafinesque (Cypselus longipennis Temminck), 

 should be considered the type. The name Hemiprocne must 

 therefore unfortunately supplant the later Macropteryx Swainson* 

 and the family name MACROPTERYGIDAE be changed to HEMI- 

 PROCNIDAE. The following species of this group are affected, 

 and should henceforth stand as follows: 



Hemiprocne coronata (TICKELL). 



Hemiprocne longipennis (RAFINESQUE). 



Hemiprocne perlonga (RICHMOND). 



Hemiprocne wallacei (GOULD). 



Hemiprocne mystacea mystacea (LESSON). 



Hemiprocne mystacea woodfordiana (HARTERT). 



Hemiprocne comata comata (TEMMINCK). 



Hemiprocne comata major (HARTERT). 



The genus of large collared swifts that commonly has been 

 called Hemiprocne must, if generically separable from Chaetura, 

 consequently be given a new name. Doctor Hartert in his most 

 recent review of the swifts, t placed Hemiprocne as a synonym 

 under Chaetura, claiming that the shape of the tail was not
