In association with the skull of the Tiger, Mr. Willcox found a 

 cervical vertebra, six lower molars and five incisors of a Horse. 

 They have the same appearance of preservation as the former and 

 are probably cotemporary fossils, though they present no distinctive 

 characters from the corresponding parts of the Domestic Horse. 

 With them there was also found a lower molar of a Llama, Auche- 

 n in minor. 



IAnguatula Diesingii from the Sooty Mangabey. — Mr. J. E. Ives 

 remarked that in preparing for maceration a specimen of Cercocebus 

 fuliginosus, he found that the great omentum contained a large 

 number of encysted specimens of Lingaatula Diesingii. The cysts 

 occurred almost invariably in the fatty portions of the membrane. 

 A few specimens also existed in the lungs and pleurae, and in the 

 peritoneal lining of the abdominal cavity. This form has not been 

 recorded before from Cercocebus fuliginosus. In 1848, Van Beneden 

 described the species from the mesentery of Cynocephalus mormon. 

 In 1849, under the synonym of Pentastomum tornatum Creplin 

 placed on record the finding of it by Gurlt in the greater omentum 

 of Macacus Cynomolgus, and by Schultze in the omentum and 

 mesentery of Cynocephalus mormon. In 1850, under the name of 

 Pentastomum euryzonum, Diesing redescribed Van Beneden's form, 

 and Dr. Leidy recorded it " from the surface of the liver beneath the 

 peritoneum " in Cynocephalus porcarius. The monkey in which 

 this parasite was found had recently died in the Zoological Garden, 

 and had been presented to the Academy by the Society.
