352 BIOLOGICAL SURVEY OF 



and four small tubercles at the distal end bear long slender 

 spines. The zooecia are attached in pairs at the ends of 

 internodes. A gizzard of a peculiar type is present. It con- 

 sists of four bluntly conical discs with teeth which project 

 into the lumen (see Osburn and Veth, 1922, p. 158, Ohio Jour- 

 nal of Science). 



Harmer (1915, p. 88) has assigned the present species to 

 the genus Buskia and states that it is closely allied to B. seti- 

 gera Hincks. In this I believe him to be correct, but in the 

 hundreds of specimens of armata I have examined I have 

 not observed the spiny protuberances for attachment at the 

 base of the zooecia, as in setigera, and the zooecial wall is 

 not transparent, but of a yellowish horn color. I have speci- 

 mens of B. setigera from Porto Rico, and it is probably cir- 

 cumtropical in distribution.
