smaller hands and longer tail of Massoutiera being the most nbvioas distinctions ; 

 but the different shape of tlie feet, as described by Lataste, affords ample reason 

 for considering Massoiitieru as distinct from Cteiiodactijlus. 



Felovia again, founded by Lataste * as a subgenus of MussoiUiera to contain 

 his M. me, I should consider sufficiently distinct from either Massoutiera or 

 Ctenodactijlas to stand as a separate genus. Besides its grooved incisors it is 

 distinguished by yet another shape of the molar teeth, its skull is peculiarly flat, 

 and its bullae are even smaller than those of Cteno<lucti/li(s qundi, the bullae 

 being immensely swollen in Ct. tali, Massoutiera nizuhi, and tlie new species of 

 Massoutiera now to be described. 



[In habits " Massoutiera " does not differ from Ctenodactijlas qaiuU. They 

 inhabit rocks with caves and hollows, and are fond of lanning along ledges and 

 under overhanging cliffs. They come out in the full sunshine, but one sees most 

 of them in the morning and towards evening. We found them generally fairly 

 shy, and they often have the habit of stopping motionless on a rock, and then 

 they are almost invisible, having the same colour as the rocks. One hears some- 

 times a short squeak, and an apparently e.xcited or angry clicking sound. The 

 tail is frequently jerked up and down, and they frequently sit up like a hamster, 

 holding food between their fore-feet, when eating. 



We found Massoutiera mzuhi only in the Mzab country, in the neighbourhood 

 of Ghardaia, and saw it once about oO km. south of the latter town. The 

 Arabs call it " gundi," and do not distinguish between it and Ctenodactylus gundi. 

 The latter is common on the rocks near Biskra and El-Kantara, and we saw young 

 ones of various sizes in April. — E. H.]

Like ^1/. mxahi, but with larger bullae. 



External characters as in M. mxahi, the pelage equally Hue and silky, and the 

 colour of the same pinkish bnff. Tail-hairs longer, flidugh this may lie an 

 accidental condition, and the tail itself longer according to the collectfir's 

 measurements. 



Sknll very similar to that of M. mzabi, bnt the bullae distinctly larger, the 

 size of the IniUae being a characteristic feature of the diftprent species of the 

 group, hi the new form the greatest breadth on the l)ullae is slightly greater 

 than the zygomatic breadth, slightly less in M. mzabi ; the inflation of the bullae 

 is greater thronghout, and their lineal diameter longer (see measurements below). 

 Incisors smooth, without any trace of the groove present in Felocia. Molars quite 

 as in M. mzahi.
