Reproduction. — Two embryos from the Congo collection are at 

 hand. One of these was taken from a specimen 810 mm., in total length, 

 killed at Medje, January 24, 1910. This embryo was 80 mm. long. A 

 female taken November 16, 1909, carried an embryo 280 mm. long, 

 which is but 22 mm., shorter than another specimen secured alive on 

 December 4, at Lukolela by another expedition. It is indicated, then, that 

 the young are approximately 290 mm. long at birth, and that they are 

 sometimes born in November or December. 



There is usually a single pair of mammae, as noted by the collector, 

 and as may be seen from examination of dried skins. A single case was 

 recorded in the field catalogue as "two pairs pectoral mammae," but I 

 am unable to discern more than a single pair on the skin of this same 

 specimen. 



Movements. — The field notes on the feeding habits of this species 

 were included in the Bequaert report. Mr. Lang's other notes concern- 

 ing locomotion were made from observations on four individuals. These 

 notes are transcribed from the field catalogue with slight alterations and 

 paragraphed separately. 



No. 1. — This specimen was an expert climber and surprisingly rapid in her 

 movements. On the ground she would cover at least four feet in a second, shuffling 

 along in a peculiar manner. When taken by the tip of her tail she would at once 

 hook the claws of her hind limbs into the large lateral scales near the base of her tail, 

 and either ascend by climbing up or, by bringing her body to a position at a right 

 angle to her tail, she would swing around hooking after everything her fore limbs could 

 possibly reach. In this position her horizontal body could make a three-quarter twist. 

 She could then look toward the ground and halfway up again toward the sky. She 

 would roll up when touched on her snout and would do this so rapidly that one could 

 hardly take one's hand away quickly enough to avoid getting caught between the 

 scales. 



No. 2. — When ascending or descending a tree of about four inches in diameter 

 this manis formed a half circle with the end of his tail, the lower surface of which was 

 kept in close touch with the bark. In going up and down oil palms he moved his tail 

 side wise and up and down, probing for and taking hold of the slightest prominence 

 with the tip of his tail. The skinny pad on the lower side was evidently of great 

 sensibility. Once he had taken hold of any prominence or small branch, he at once 

 worked freely with his fore limbs, as he could hold and direct himself when fastened 

 only by his tail. As a rule, however, he used his hind limbs in keeping any position 

 lasting more than a moment. 



No. 3. — This young manis was still alive. Put upon the back of a dead though 

 still unskinned male, it at once climbed toward the tail, grasping it firmly on the 

 edges, and put its tail around the tail of the adult specimen. When the adult speci- 

 men was shaken the young seemed not to be troubled in the least. The trial was re- 

 peated several times, and every time it selected the tail to which to attach itself, some- 

 times with the head forward, sometimes backward. It is quite certain that the young
