new Mammals from Chlriqui. 379 



D. ecaudata ; interorbital region narrou'er. Zygomata more 

 widely and evenly spread. Bullae larger and higher. 



Upper teeth apparently quite as in D. ecaudata, but below 

 the last three cheek-teeth (/?3, jc^, and vi^ are subequal in 

 size, while in three South-Brazilian examples of D. ecaudata 

 the penultimate {p^ is fully twice the size of w/j, and half 

 as large again as p^- Lower canine rather shorter, and 

 with a more strongly marked posterior basal ledge. 



Dimensions of the type : — 



Forearm 54 millim. 



Head and body 87; ear 15; third finger, metacarpal 54; 

 first phalanx 11, second phalanx 28. 



Skull : greatest length from tip of incisors 22*8 ; basal 

 length from same point 17*2; zygomatic breadth 12*6; 

 breadth of brain-case 11'3 ; palate length 7; post- palatal 

 length 10-2. 



Hah. Boquete, 4500 feet. 



Type. Adult male. B. M. no. 3. 3. 3. 3. Original 

 number 62. Collected 4tli March, 1902. One specimen. 



In spite of their general resemblance to each other the 

 difference in the proportions of the lower teeth seems to 

 necessitate the distinction of the Central-American DipJiylla 

 from that of Brazil. 



Bassariscus Sumichrasti nottnus, subsp. n. 



Size rather smaller than in B. S. variabilis, Pet.*. General 

 colour approximating to " smoke-grey," though slightly more 

 olivaceous, lighter and less heavily black-lined than in 

 variabilis. Across the shoulders especially the colour is a 

 much clearer grey than in that form, and there is but little 

 trace of the mesial dark nuchal band. Muzzle and orbital 

 rings brown; the forehead lighter, but divided between the 

 eyes by a dark line. Cheeks and patch behind eyes white. 

 Outside of ears more thinly haired than in variabilis, and 

 only brown for their basal halves, the terminal halves light- 

 ening to white on the edges. Postauricular dark patch 

 present, but less developed than in variabilis. Under 

 surface dull buffy white, more or less mixed with grey. 

 Upper surface of hands and feet grizzled fawn-grey, dark- 

 ening nearly to black on the digits, but with less black than 



* In the absence of good specimens of the geographically more dis- 

 tant B. Siaiiick)-asti the comjiarisons are made -with the Guatemalan 

 J5. variabilis, of which the JJiitish Museum possesses several excellent 

 specimens from the Volcan de Fuego, Guatemala, agreeing absolutely 

 with Peters's description and tigures of the skull.
