Skiill and dentition. — Piijicipal cliaracters of teeth as in 

 Ft. anetianus — i. e. upper incisors with strong posterior ledges, 

 ig enlarged, about three times the bulk of ij, pi eidarged, 

 about twice the size of ig, p^ (second upper premolar) with 

 distinct small antero-internal tubercle, the posterior ledge of 

 P4, nij, and m2 continued forward along inner side of teeth — 

 but individual teeth noticeably heavier. 



Measurements of skull J : — Total length to gnathion 

 *62-5 mm. (55-7-58) ; from front of orbit to tip of nasals 

 *18-2 and fl^'S (15-2-16'2) ; width of brain-case at zygo- 

 mata *23-5 (21-22) ; zygomatic breadth *38-5 (31-7-32-7) ; 

 across crowns of m^-m^ (externally) *17'5 and tl8 (14."8- 

 ]5-8) ; length of lower jaw from condyle *50-5 and f-^S 

 (42-8-44-8J'; c-m^ (crowns) *23-5 and t23 (20-8-22) ; c-mg 

 (crowns) *26-3 and t25-2 (22-8-23-7). 



Measurements of teeth: — p^ (second postcanine tooth, 

 above), length (antero-posterior extent) *4'7 and t4"5 (4*2- 

 4-6), breadth *3'5 and i-3-3 (2-8-3) ; pS length *5 and fl'S 

 (4-2-4-7), breadth *3-6 and t3-7 (3-3-2) ; m^ length *5-7 

 and t5-8 (5-5-4), breadth *3 and t3 (2-7-2-8) ; m^, length 

 'i'2-2 and t2'2 (1-9-2-1), breadth *l-5 and t2 (1-7-2) ; pi, 

 length *2-8 and t2-7 (2-2-2-7), breadth *2-2 and t2-5 (2-2-2); 

 ps (second postcanine tooth, below), length *4-8 and +4*5 

 (4-5-4-8), breadth *3 and t2-9 (2-7-3) ; p^, length *5 and 

 t4-8 (4-2-4-8), breadth *3 and t3 (2-7-2-8) : m^, length *5-I 

 and ti-8 (4-5-4-9), breadth *2-9 and t2-9 (2-5-2-7); mg, 

 length *3-5 and t3-8 (3-7-3-8), breadth *2-5 and t2-7 (2-2- 

 2-5) ; nis, length *l-8 and fl'S (1-7-1-8), breadth *l-2 and 

 tl-8 (1-4-1-7). 



Wings. — The greater length of the wings of Pt. eotinus, 

 as compared witii Pt. anetianus, appears to be due chiefly to 

 a lengthening of tlie three long metacarpals and of the second 

 phalanx of the third (longest) finger ; the other phalanges 

 and the forearm would seem only to average a little longer 

 than in Pt. anetianus. 



Forearm *132 and tl28-5 mm. (123-5-130); third finger, 

 metacarpal *89 and \^l'b (80-83), first phalanx *d6 and 

 tG7-5 (61-5-66), second phalanx *93-5 and t95 (81-5-90-5); 

 fourth finger, metacarijal *87 and t85-5 (78-5-81), first 

 phalanx *56 and t55 (51-56), second phalanx *50-5 and 



I Measurements of the type of Pt. eotinus are marked with an asterisk, 

 those of the paratype with a dagger ; between parentheses are added, for 

 comparison, the minimum and maximum measurements of a series of 

 Ft. anetianus (copied from Cat. Chir. 2 ed. i. pp. 291-292).
