(3) Hinder chamber of auditory bulla always everted. 
(4) Anterior margin of opening of external auditory meatus more 
projecting than the posterior margin. 
(5) Floor of external meatus or adjacent part of bulla with a fora- 
men and fissure in a deep pit. 
(6) Angle of mandible sometimes everted. 
(7) Mastoid always prominent. 
(8) Paroccipital processes depending below bulla. 
(9) Aperture of auditory meatus small and triangular. 
(10) Alisphenoid canal always very short. 
(11) Carotid artery perforating or notching the sphenoid, there 
being a conspicuous carotid foramen in the basis cranii. 
(12) Never any prescrotal glands’. 
(18) Anus very generally not opening on the surface of the body, 
but in a sac or cutaneous invagination. 
(14) Anal glands sometimes in several pairs. 
(15) A supracondyloid foramen to humerus. 
(16) An alisphenoid canal, in rare instances not completely enclosed 
by bone, but then its place indicated by bony processes. 
(17) Pollex alone, or both pollex and hallux sometimes absent. 
(18) Caecum always present, but small or moderately long. 
(19) Tarsus and metatarsus hairy or bald. 
A very different animal from any hitherto here reviewed is that 
to which the generic name Galidictis was given in 1837 by Isid. 
Geoff. St.-Hilaire*, and again by him in the Magasin de Zool. 1839— 
1841, where the external form and skull, including the basis cranii, 
are well represented, and a full description given in a long note 
beginning on page 32. It is also the Mustela striata of Geoffroy 
St.-Hilaire (Cat. des Mamm. p. 98), and the Putorius striatus of 
Cuvier (Régne &c. 2nd edit. p. 144). The external form has been 
figured in our P. Z. S., 1848, pl. 1, witha short description and notes 
as to habits on page 21. The skull is also given by De Blainville 
(Ostéog., Viverras) on pl. 5, and the dentition on pl. 12, under the 
name Mangusta (Galictis) striata, ‘Vhere are two species, both from 
Madagascar—one the original G. striata of Isid. G. St.-Hiliare, and 
the other G. vittata, described and figured by Gray (P. Z. 8. 1848, 
p- 21, pl. 1) the skin and the (immature) skull of which are in the 
national collection, where are also four skins and two skulls of the 
former species. The length of the head and body of the latter is about 
35"°5, of the tail 33". In each species the body bears longitudinal dark 
stripes on a lighter ground. The claws are long, but considerably 
curved (cf. fig. 14, 1, p. 192). The claw of the pollex reaches to 
the end of the proximal phalanx of the index, and that of the fifth 
digit to the end of the proximal phalanx of the fourth diyit, which 
is slightly longer than the index, the median being the longest. The 
claw of the hallux reaches nearly tothe end of the proximal phalanx 
of the index, and that of the fifth digit of the pes nearly to the 
' The nature of the prominence in Swricata has to be seen.
