Professor Jacoby was prevented from presenting the paper 

 that had been announced because his photographs had failed to 

 arrive. In his place Professor Rees threw upon the screen with 

 the lantern some photographs of pairs of smaller planets, which 

 had been taken by Professor Wilson, of Minnesota. 



Considerable discussion ensued, after which the section ad- 

 journed.

Stated Meeting. 



January II th, 1897. 



The meeting was called to order by Professor Bristol. Twenty- 

 five persons present. 



Dr. G. S. Huntington read a paper entitled " A Contribution 

 to the Mj'ology of Lemur bruneus.''^ 



The paper deals with some of the ventral trunk muscles and 

 the appendicular muscles of the forelimb and pectoral girdle. A 

 comparison of the structure of these muscles with the corre- 

 sponding parts in other members of the suborder shows L. hru- 

 neus to possess marked primitive characters in the arrangement 

 of the pectoral girdle muscles and the muscles of the proximal 

 segment of the anterior limb. This is especially evident in the 

 lateral recession of the pectorales, the compound character of 

 the ectopectoral insertion, the junctions of a Pectoralis abdomi- 

 nalis with the typical entopectoral insertion, and the presence 

 of an axillary muscular arch, derived from the tendons of the 

 Latissimus dorsi and connected with the deep plane of insertion 

 of the ectopectoral tendon. 



The presence of a third or inferior portion of the coraco- 

 brachialis is noted in addition to the upper and middle portion 

 usually present in the Lemuroidia. 



The ventral trunk muscles present a distinct carnivore t^^pe 

 in. their ari-angement, instanced by the high thoracic extension
