Show 730 MR. G. E. DOBSON ON THE MOLOSSI. [Nov. 7, cent; keel very deep, projecting outwards beyond the antitragus, but also very slender, curved backwards and upwards; tragus small, quadrate, superior margin straight or very slightly concave, upper half of outer margin concave, lower half forming a prominent angular projection; antitragus considerably longer than high, terminating in front between the eye and the angle of the mouth (fig. 6), separated posteriorly by a deep notch. Face deeply grooved horizontally beneath the eye, which is remarkably prominent and directed forwards. Muzzle slender, concave between the ears and the projecting, sharply cut superior margin of the nostrils ; nasal apertures directed almost laterally, separated by a wide space, which is divided in the middle Fig. 6. Head of N. macrotis. by a raised vertical ridge. Upper lip deeply furrowed by oblique wrinkles. No gular sac. Thumb rather short, with a small callosity ; terminal phalanx of third finger very short. Wings from the distal third of the tibiae. Fur short, reddish brown above and beneath; on the upper surface extending upon the wing-membrane as far outwards as a line drawn from the middle of the humerus to the knee-joint, on the base of the interfemoral, and outwards behind the forearm in a narrow band to the carpus. Teeth slender, with very acute cusps. Lower incisors 4, crowded, bifid. First upper premolar small, but acutely pointed, in the centre of the space between the canine and the second premolar; second premolar large, with a long and very acute internal basal cusp. Length (of the type specimen, an adult § ) : head and body 2"*8 ; tail 1"*9, tail free from membrane 1"*0; head 1"*1; ear 1"*0, tragus 0"*15x0"*l; forearm 2"*2; thumb 0"*3; second finger-metacarp. 2"-l, 1st ph. 0"*9, 2nd ph. 1"*0; third finger-metacarp. 2"*0, 1st ph. 0"75, 2nd ph. 0"*1 ; fourth finger-metacarp. 1"*0, 1st ph. 0"7, 2nd ph. 0"*3; tibia 0"*65 ; foot and claws 0"*4. Hab. Cuba; Brazil (Mato Grosso); Paraguay. The next species, N. gracilis, resembles N. macrotis very closely in general structure, and forms with it a separate section of the genus, distinguished by the peculiar shape of the muzzle. |
