A second specimen of Pterygistes azoreum Thomas. 



The United States National Museum contains an adult female of 

 Pterygistes azoreum Thomas, a bat otherwise known from the type only, 

 a male collected on the Island of St. Michael, and now in the British 

 Museum. It \vas taken on the Island of Terceira, November 7, 1894, by 

 Dr. Wm. Trelease, and agrees closely with the characters given in the 

 original description, except that the forearm is longer and the foot 

 smaller than in the type. Measurements (those in parenthesis are of 

 the British Museum specimen) : total length, 97 (96) ; head and body, 

 50 (54); tail, 43 (42) ; tibia, 16.6 (17); foot, 7; foot without claws, 6 (7.7); fore 

 arm, 42 (37) ; thumb, 6 ; second digit, 42 ; third digit, 72 (62) ; fourth 

 digit, 59 ; fifth digit, 48 (43.7) ; ear from meatus, 12 (12) ; ear from crown, 

 10; width of ear, 11 ; greatest length of skull, 14.6 (14.2) ; basal length, 

 14; basilar length, 12 (11); zygomatic breadth, 9.6 (9.4); interorbital 

 constriction, 4.6 (4.4) ; maniible, 10.4; maxillary toothrow (exclusive of 

 incisors), 5.4 (5.1) ; mandibular toothrow (exclusive of incisors), 6.

The status of Nyctinomus nevadensis (H. Allen). 



In March, 1894, Harrison Allen described a freetailed bat of the genus 

 Nyctinomops, from " Nevada and California," as Nyctinomus macrotis 

 nevadensis (Monogr. Bats N. Amer. p. 171, March 14, 1894). A few 

 months later J. A. Allen showed that the animal is specifically distinct 

 from the West Indian Nyctinomus (Nyctinomops} macrotis (Bull. Amer. 

 Mus. Nat. Hist., VI, pp. 326-328, November 7, 1894). Both writers appar 

 ently overlooked the fact that this bat had already been described by Ward 

 from Mexican material as Nyctinomus depressus (Amer. Nat., XXV, p. 

 747, August, 1891). Having examined several Mexicans specimens 

 which perfectly agree with Harrison Allen's type and with Ward's very 

 detailed discription, I have no hesitation in placing Nyctinomus macrotis 

 nenadensis H. Allen as a synonym of Nyctinomops depressus (Ward).

The generic position of Nyctinomus orthotis H. Allen. 



Among the bats of the genus Nyctinomops I recently mentioned the 

 Jamaican Nyctinomus orthotis of Harrison Allen (Proc. Acad. Nat. Sci., 

 Philadelphia, 1902, p. 393, September 12, 1902). This I did quite inad 

 vertently, as the species is in reality a member of the genus Provnopt, 

 closely allied to the Central American P. glaucinus. It should stand, 

 therefore, as Promops orthotis (H. Allen). Gerrit S. Mitter, Jr.
