or so ago — from another bird-store man in Washington, a dead 

 specimen of a species of marmoset. As it was not immediately 

 convenient to compare the animal with museum or other material, 

 with the view of identification, and taking it to be one of the ordi- 

 nary little "cotton-head" monkeys of Brazil, this step was, for 

 the time, postponed. However, rare or otherwise, I went at the 

 material in my usual way; and after carefully examining its 

 topographical anatomy, I placed the animal on its side, in such a 



position as to exhibit most of its 

 characters, making a photograph of it 

 nearly natural size. A reproduction 

 of this photograph illustrates the 

 present article. Having previously 

 made measurements of total length, 

 limbs, tail, etc., the hide was care- 

 fully removed ; this was poisoned and 

 made into a "flat skin." A com- 

 plete skeleton of the specimen was 

 obtained, labeled, and put away for 

 future use. Observations were made 

 upon the "soft anatomy" of the 

 animal, which closed the record for 

 that particular specimen. Later on, 

 upon showing the photograph to Mr. 

 Gerrit S. Miller, Jr., Curator in 

 charge of the Division of Mam- 

 mals of the U. S. National Museum, I was informed, much to my 

 surprise, that my marmoset was a specimen of the very rare 

 Seniocehus meticulosus, of Northern Colombia, of which it consti- 

 tuted the fourth example known to science. So rare is the form 

 that Dr. D. G. Elliot, in his recent and elegant three- volume 

 work on "A Review of the Primates" (Monograph American 

 Museum of Natural History, 19 12), awards this species the colored 

 frontispiece of volume one, the same having been made by Mr. 

 Fuertes. My "flat skin" now forms a part of the collection of 

 mammals of the United States National Museum ; the skeleton is 

 in my private collection and will be described later on. Dr. 

 Elliot has already given us figures of the skull in his work. Thus 

 it will be seen that nothing is lost by making records of all material 

 that comes into one's work-shop.
