168 INDEX GENERUM MAMMALIUM. 
Centronycteris (subgenus of Proboscidea) Gray, 1838. Chiroptera, Noctilionidee. 
Mag. Zool. & Bot., II, No. 12, p. 499, 1838; Zool. Voy. H. M. 8, ‘Sulphur,’ Mamm., 
pt. m, 1843, 23* (raised to generic rank); List Spec. Mamm. Brit. Mus., 
Da xix 843. 
Type: Vespertilio calcaratus Maximilian, 1821,t from Fazenda, near Coroaba, on the 
Rio Jucu, near the Rio do Espirito Santo, Brazil. 
Centronycteris: kévrpov, point, spike; vvKrepis, bat—probably in allusion to 
the tip of the tail; the last caudal vertebra alone projects beyond the inter- 
femoral membrane. 
Centurio Gray, 1842. Chiroptera, Phyllostomatide. 
Ann. & Mag. Nat. Hist., X, 259-260, Dec., 1842; Zool. Voy. H. M. 8. ‘Sulphur,’ 
Mamm., pt. 1r, 26-28, pl. vu, 1843. ; 
Type: Centurio sener Gray. In the description the locality is given as ‘Amboyna;’ 
the species, however, is only known from tropical America—Mexico and Cuba. 
Centurio: Lat. centurio, a centurion or commander of a company of infantry, cor- 
responding to a captain in a modern army, whose insignia of rank is the 
shoulder badge or epaulet. The type species of the genus was described by 
Gray as having small epaulet-like tufts of white hair on the shoulders, a char- 
acter which evidently suggested the common designation *epaulet bat,’ as well 

as the generic name. 
Centuriosus (subgenus of Sus) Gray, 1862. Ungulata, Artiodactyla, Suidee. 
Proc. Zool. Soe. London, 1862, 17; Ibid., 1868, 40-41 (raised to generic rank). 
Type: Sus pliciceps Gray, from Japan. 
Centuriosus: Centurio + Sus—in allusion to the wrinkled face. 
Ceonix TremMMINCK, 1827. Marsupialia, Phalangeridee. 
Mon. Mamm., I, 1ére Mon., 10-12, pl. 1 figs. 1-3, pl. 1 figs. 1-5, pl. rv, 1827.

Type: Phalangista ursina Temminck, from the northern part of Celebes.  Provi- 
sional name. ‘‘J’avais eu l'idée de former des Couscous un genre sous le nom 
de Ceonix; mais ces coupes nombreuses me paraissent parfaitement inutiles, 
et sont à charge à la mémoire, lorsqu'elles ne reposent pas sur des caractéres 
faciles à saisir."  (TEwMMINCK.) 
Ceonix: Kéw@=KE1w, to cleave; 0v 08, claw—in allusion to the long, curved claws. 
Cephalogale JourDAN, 1862. Fer:e, Canide.

+ The specific name is preoccupied by V. calcaratus, Rafinesque, 1818, from North 
America, and has been replaced by Saccopteryx wiedi Palmer (Proc. Biol. Soc. Wash., 
XII, 110, 1898).
