^vitliout break, when viewed from aliove. In j^siluruft ihcvct 

 is a stront; pri»jcciion forwarcls, as correctly shown in fig. 1, 

 this projection being less, thongh still evident, in the younger 

 specimens which alone I hud previously been able to see. 

 Througiiout the series this difference is quite marked if 

 specimens of corresponding age are compared, though the 

 projection of old epsilanus is equal to that of young psilurus. 

 Zygomata somewhat more widely spread. Interorbital 

 region narrower, the crests approaching each other above 

 much more closely anteriorly than on the })arietals, these 

 ridges being practically parallel in psilurus. Mesopterygoid 

 fossa slightly broader. 



Dimensions of the type (measured in flesh) : — 



Head and body 209 mm. ; tail 43; hind foot 36. 



Skulls of old male and female, the first the type : condylo- 

 basal length 4^^'5, 47 ; condylo-incisive length 49, 40 ; 

 zygomatic breadth 37'3, 32*6; nasals 18"3 x 9, 17'4x8; 

 interorbital breadth across ridges on upper surface 4*7, 6*4; 

 breadth across ridges on parietals 8, 10; posterior breadth 

 on transverse ridges 31,28; palatilar length 25*7, 24*5; 

 palatal foramina 5*8, 5'4 ; upper molar series (alveoli) 11, 

 10-8.

'fi/pe. Old male. B.M. no. 10. 5. 1. 75. Original number 

 40. Obtained 15th June, 1908, by Mr. Atan Owston's 

 collector Orie. Ten specimens examined. 



This species is separable from M. psilurus by the different 

 structure of the anteorbital region and parietal crests, these 

 differences not coming out in comparison with the younger 

 examples of Milne-Edwards's species^ which alone I was 

 able to examine in 1909. The respective localities of the 

 two animals arc about 1200 kilometers apart. 



The specific name refers to the epsilon-like form of tho 

 upper molars, especially vi^.
