Mistonj. — The genus CMlonycteris was founded by Gray in 1839 on 

 the Cuban C. madeayii, the describer believing the genus to be inter- 

 mediate between "the Saccopteri and the genus Mormoops," the latter 

 genus being considered by him a member of the tribe Noctilionina. 

 In 1840, Gundlach described the genus Lobostoma based on two species, 

 one of which is the Cuban representative of the genus Mormoops, the 

 other a synonym of CMlonycteris madeayii. The same year Wagner, 

 in the first supplementary volume of the Saugthiere, associated the genus 

 with Mormoops, and placed them in the tribe Brachyura of the Gymno- 

 rhina. During the year 1843 this genus received considerable atten- 

 tion from Wagner and Gray, the former of whom described C. per- 

 sonata, C. ruhiginosa and C. gymnonotus, all from Natterer's Brazilian 

 material. The last of these three species has since been removed to 

 Dermonotus {=Pteronotus auct.). Gray's work consisted of the de- 

 scription of the Haitian C. fuliginosa and Phyllodia parnellii from Ja- 

 maica, the rather different character of the latter form having impressed 

 him to such an extent that he created a genus for it. In comment- 

 ing on Phyllodia he says it is "& Noctilionine bat, with an apparent 

 nose-leaf, bearing a much greater resemblance to the Leaf-nosed Bats 

 (Phyllostomina) than even Mormoops, which, when he first described 

 it, Dr. Leach referred to that group." The Jamaican C. grisea was 

 the next form described, Gosse also giving us a figure. Burmeister, in 

 1854, in his system of Brazilian mammals, associated CMlonycteris 

 and Dysopes, and placed them in the Gymnura; while Wagner, in 1855, 

 placed it and Mormoops with the Noctilionine bats in the section 

 Brachyura of the Gymnorhina. The year 1861 witnessed the de- 

 scription of two more species of the genus, C. boothi from Cuba by Gund- 

 lach, and C. osbiirm by Tomes from Jamaica, the latter being Gray's 

 Phyllodia parnellii. Koch in 1862-63^ used the term Mormopida in 

 an indefinite way, apparently for this association of genera; while 

 Ciray, in 1866,^ used the term Mormopsina for Mormoops, and Phyllo- 

 diana for Phyllodia, CMlonycteris and Pteronotus. Peters, in his 

 synopsis of the Mormopes, published in 1872, associated CMlonycteris 

 with Mormops in the above group. Gill, in the same year,^ proposed
