that it might at first sight appear that the two belonged to the same genus. The 
Machcerodu-s, however, agrees with other species of that genus in the absence of m. 2, 
and the talon and inner cusp of m. 1. 
That the present jaw is generically distinct from all other forms is apparent 
from the foregoing comparisons ; which also show that it presents characters 
connecting the hyaenine Lepthycena with the feline Machcerodus * palceindicus. The 
connection between those two genera is indeed rendered so close that it is probable 
no well-marked distinction can be drawn between the families Hycenidce and Felidce ; 
and it is not improbable that through an ally of the present form, some of the 
machserodonts may have descended from an ancestral stock intimately related 
through Lepthycena with the viverroids. The present jaw is provisionally referred to 
the Felidce , under the new name of Mluropsis annectans ; and it is much to be hoped 
that future finds may bring to light other remains of this very interesting form. 
Genus II. : iELUROGALE, Filhol. 
General. — The main characters of this genus have been given in the table on 
page 314 : it has been hitherto known only by the single species M. intermedia }i 
Filh., from the Quercy phosphorites ; although there is great variation in the size of 
that species, and it has been divided into the races major and minor} 
Species : vElurogale sivalensis, n. sp., nobis. 
Syn. Pseudcelurus sivalensis, nobis. 
History . — In 1877 the present writer gave a preliminary notice 2 of the right 
ramus of the mandible of a feline carnivore, collected by Mr. Theobald in the 
Siwaliks of the Punjab, under the name of Pseudcelurus sivalensis. The more 
elaborate descriptions of the European forms of that genus, published since that 
notice was written, have shown that the Siwalik form is generically distinct, and 
probably belongs to the genus JElurogale ; founded subsequently to the original 
naming of the Siwalik fossil. 
Mandible. — The mandible mentioned above is represented of the natural size in 
plate XLIV., figs. 7, 7a : it is broken off a short distance behind m. 1 ; and anteriorly 
has lost the portion containing the incisive alveoli, and the upper part of the root of 
the canine. There remains a considerable part of m. 1 ; the alveoli of pm. 4 and 
pm. 3 ; the base of a minute pm. 2, and part of the root of the canine. Of m. 1 the 
anterior lobe of the blade remains perfect, but has its summit abraded : the hinder 
lobe is broken off, but the elongated shape of its alveolus, and the long interval 
between the sockets of the two fangs, indicate that this tooth was furnished with a 
talon : the inner cusp being, however, absent. The alveoli of pm. 4 and pm. 3 are of

quel. Mam. Foss. d. Phos. d. Quercy,” p. 8).
