inner digits. In Hywna and Crocuta it only goes to the second, 

 third, and fourth digits. 



The tibialis posticus is as in the Cat. 



The flexor longus digitorum and flexor hallucis of the Genet are 

 like those of the Cat, save that a small tendon is sent to the 

 hallux. There is no such tendon in the HycenintB. 



The fiexor brevis digitorum is in the Genet as in the Cat, save 

 that it is not divided into four bellies side by side, but is in one 

 mass '. In Crocuta - it is confined to the sole of the foot, and is 

 represented solely by a tendon, there being no muscular belly. In 

 H. striata (according to Meckel) it is a prolongation of the tendon 

 of the plantaris with additional muscular fibres from the fourth 

 metatarsal. In the Civet it seems to be similar, except that the 

 additional muscular fibres are derived from the os calcis. 



The accessorius of the Genet (and apparently of the Civet) is 

 very unlike the muscle described by me under this name in the Cat *. 

 It arises from the outer side of the os calcis, and ends in a strong 

 tendon which joins obliquely the tendon of the deep flexors pre- 

 viously noticed. In Crocuta it is very small and slender, with a 

 similar origin and insertion. 



In the Genet, Civet, and Croew^a there are but three lumbricales, 

 which take origin from the surface of the conjoined deep flexor 

 tendons. 



Dr. Watson and Mr. Young remark* of the HyceniruB \ — "The 

 enormous development of the muscles of the neck and fore quarters, 

 together with minor points already referred to, serve at once to 

 associate " Crocuta with the other Hysenas, and to separate them 

 " from the remaining groups of the iEluroidea." Doubtless also, as 

 these authors remark, the external form and skeleton of Proteles 

 indicate that its muscular system does not difl'er materially from that 

 common to Hyana and Crocuta, 



Splanchnology. 



Tongue. 



The tongue in the Felidce is provided with circumvallate papiUcB 

 disposed in two rows converging posteriorly, there being sometimes as 

 many as six in each row. Behind these is a group of very large, soft, 

 and T^omttA flattened papillce. Fungiform papilla are little conspi- 

 cuous, but are scattered over the organ, especially at the sides of the 

 anterior part. The conical papillcB have, at the anterior fourth of the 

 dorsal surface, that well-known hard and horny character which 

 gives a rasp-like character to the tongue of even small Cats, while in 

 the large species these papillae are like claws and are veritable 

 spines.
