38 ATELEUS 



similar specimen, which died twenty-six days afterwards. It was a 

 young half grown male. I have compared its skin with the typical 

 specimen of A. griscescens, now in the British Museum, and believe 

 them to be probably identical. The young animal is, as might be 

 expected, rather lighter in color, particularly below, but above exhibits 

 the same mixture of black and grayish hairs as in the original. The tail 

 is nearly black above, with a light line of grayish hairs below. The 

 length of the body is fourteen inches, of the tail sixteen inches. There 

 is no rudiment of a thumb apparent. 



"It is possible this may be a good species, and still turn up in 

 some part of the Central American or Colombian Coast, whence Mr. 

 Greey's specimen probably came, but I do not yet consider it sufficiently 

 well established." 



This specimen, described by Dr. Sclater, I found in the Collection 

 of the Paris Museum. 



A skull in the Paris Museum stated to have been obtained from 

 the Zoological Society of London bears upon it the name "Ateles ( !) 

 ciNERASCENS." This is evidently an error as there is no Spider 

 Monkey with that appellation. It was most probable that griscscens 

 was the word intended to have been written, and it doubtless belonged 

 to Sclater 's example. The dimensions of this skull are as follows: 

 total length, 119; occipito-nasal length, 99; Hensel, 69; zygomatic 

 width, 62 ; intertemporal width, 47.5 ; breadth of braincase, 59 ; median 

 length of nasals, 17 ; length of upper molar series, 25 ; length of 

 mandible, 62 ; length of lower molar series, 29. 



As the type of A. cucull.\tus was without a skull, no comparison 

 between it and the one from which the measurements given above 

 were taken, could be made.
