Lemuravas, g. n. (foss.), O. C. Marsh, Am. J. Sci. (3) ix. p. 239, allied 
to Lemur, but with more numerous teeth ; type, L. distans, sp. n., Eocene 
of Wyoming. 
'dUyopsodus, Leidy, belongs, not to the Ungulata, but to this order, and 
is related to Lemuravu^ ; id. tom. cit. p. 239. 
Sarcolemur, g. n. (foss.), E. D. Cope, P. Ac. Philad. 1875, p. 256, allied 
to Pantolestes, Tomitherium, and Anaptomorphus, but differing in denti- 
tion, and regarded as showing relationships to the lower Carnivora ; type, 
Antiacodon furcatus, Cope, Eocene of N. America. 
The following fossil forms from the Eocene of New Mexico are re- 
ferred to (from “ Report on Vertebrata of New Mexico, An. Rept. Chief 
of Engrs. 1874,” and “ Yertebrata of the Eocene, Geogl. Ex. and Surv. 
W. of 100th M. 1875”) by E. D. Cope, in G. M. Wheeler’s Ann. Rep. 
Geog. Expl. & Surv. 1875, pp. 93 & 94 : they are apparently new, and 
their position is still uncertain ; they are probably, however, referable to 
the Primates : —

OHIROPTERA. 
G. E. Dobson gives a “ Conspectus of the Sub-Orders, Families, and 
Genera of Chiroptera arranged according to their natural affinities,” Ann. 
N. H. (4) xvi. pp. 345-357. The first sub-order is named Megachiro- 
PTERA (= Chiroptera Frugivora, auctt.), with one family {Pteropidce) ; 
the second Microchiroptera (= Chir. Insectivora) with seven families, 
arranged as follows : — 
A. Tail contained within the interfemoral membrane. “ Vespertilio- 
nine Alliance.” 
a. Middle finger witli two phalanges. 
a'. First phalanx of the middle finger extended (in repose) in a line 
with the metacarpal bone. 
a". Nostrils opening in a depression on the upper surface of the 
muzzle, surrounded by foliaceouS cutaneous appendages. 
a"'. Tragus none ; premaxillaries represented by osseous laminae in 
middle of muzzle. 
Fam. I. Rhinolophidce (sub-lf. Rhinolophince and PhyllorhinincB) . 
b'". Tragus distinct ; premaxillaries cartilaginous or smaller, sepa- 
rated in front. 
Fam. II. Nycteridce (sub-ff. Megadermince and Nycterince). 
b". Nostrils opening at extremity of muzzle, without distinct appen- 
dages ; premaxillaries small, widely separated ; tragus distinct. 
Fam. III. Vespertilionidce. 
B. Tail perforating the interfemoral membrane and appearing on its
