A CUBAN CHIMPANZEE 331 



Lastly, the young chimpanzee, product of the relations be- 

 tween Jimmy and Cucusa, was baptized with the name of Anuma 

 (a Simian divinity of India). It was born on the 27th of April, 

 1915, a date from now on memorable in the calendar of births 

 of anthropoid apes. 



About Jimmy I have very little to say, except in reference 

 to the original posture that this ape takes in the act of repro- 

 duction. It is known that even in their most intimate acts the 

 apes show the least possible modesty; and, due to this peculi- 

 arity, observers have been able to be present during the act of 

 generation, coram populo, and to witness the classic position, 

 more canum, in this interesting species of animals. Jimmy, 

 however, presents an exception to this classic position. When 

 this master and lord of the cage experiences ardent desires of 

 possession (and this happens very frequently), he sits on the 

 floor, stretches his legs out close to each other, and strikes the 

 floor with the dorsal side of the hands, the fingers relaxed. This 

 signal must be well known to the female, because, whenever 

 she is surprised by it, she turns her head and, without the slight- 

 est vacillation, very passively comes to the male, who is wait- 

 ing in the posture already described. Then she turns her back 

 to him and sits on his thighs, opening her legs at the same time 

 that she executes a movement of inclination towards Jimmy's 

 feet, — prostrating herself, in other words, in the attitude of a 

 Mussulman praying. During the act, the female remains pas- 

 sive until the end, the male assuming all the active part of 

 the function. 



With regard to Cucusa, pregnancy was first suspected in 

 the month of August, 1914, because, at the catamenial period, 

 the genital turgency was moderated while there was also a 

 decrease in the flow of blood. These symptoms were signifi- 

 cant, as it is known that at these periods the development 

 of the external genital parts reaches a voluminous size. During 

 this period also, Cucusa's usual joviality disappeared; at the 

 same time, she was losing appetite, showing a certain dislike 

 for food, which was expressed sometimes in actual vomiting.
