192 On a Collection of Bats from Para. 
Artibeus gamaicensis, Leach. 
One. 
This appears to me to be the name which should be borne 
by the common bat called by Dobson A. perspicillatus, Linn. 
Linnzus’s name * was founded primarily in the tenth, and 
solely in the seventh (quoted in the tenth) edition of the 
‘ Systema,’ on Seba’s Vespertilio americanus vulgaris, plate lv. 
fig. 2 of the ‘ Thesaurus.’ Now that animal is clearly not an 
Artibeus, and in my paper on Seba’s mammals I have 
identified it with a bat referable to what is usually known as 
Hemiderma brevicauda, and this latter therefore I believe 
ought to be called Hemiderma perspicillatum, Linn. 
‘The next name for the Artibeus 1s yamaicensis, Leach, 1822, 
and that may provisionally be used for it. Should southern 
specimens require to be separated from the northern, their 
name would be Arétbeus lituratus; Phyllostoma lituratum, 
Licht. }, founded on Azara’s Chauve-souris Premier, dating 
from 1823. Wied’s “ superciliatum’’ would also be available 
for the Brazilian animal if the Jamaican form proved distinct, 
as, indeed, Dr. Allen considers it to be. 
Artibeus cinereus, Gerv. 
One. 
Vampyrops zarhinus, H. All. 
One. 
This bat may be readily distinguished from all species of 
Vampyrops hitherto known by the extremely small size of the 
incisors, which do not touch one another. This character is 
also shared with the species described in the footnote §. 
* Syst. Nat. (10) i. p.31 (1758). In cases such as this, Didelphis mar- 
supialis, and others, where Linnzus in his tenth edition quotes earlier 
works of his own, I think it would be advisable that such earlier works 
should be the guiding basis for selection among his references. It seems 
contrary to common sense that elimination or any other method should 
be permitted to bring a Linnean name on to an animal not mentioned at 
all in the first giving of the name by Linnzus himself, even though such 
first naming may, as “ pre-Linnean,” be technically invalid.

§ Vampyrops recifinus, sp. n. 
Allied to V. lineatus and V. zarhinus. Striping strongly marked, the 
upper white facial line broad and conspicuous, the lower evident, and the 
dorsal line clear and continuous. Nose-leaf much as in V. zarhinus, the 
sides of the horseshoe with an infolded lobule about their centre. 
Distribution of fur, shape of ears and tragus as in V. zarhinus. General 
colour brown, rather paler below. Wing-bones white, contrasting with 
the brown membranes. 
Skull shaped as in V. zarhinus, and with the same minute and separated
