Summary. — This worm, found in the stomach of the sea lion of Bering Sea, is iden- 

 tical with the form described by Rudolphi in 1802, as detiued by Schneider in 186G. It 

 is also found in Iceland, Greenland, and elsewhere. In detail its history is as follows: 



Historical review, — Rudolphi (1802, jip, 14, 15) was evidently the first to 

 describe Ancaris oscidato ; his article is not at our disposal at present. The following 

 year Zeder (1803, p. 105) placed Rudolphi's species in the genus Fusaria, giving the 

 following short diagnosis, taken from Kiidoliihi: 



Osculata Fusar. capitis corpore angustioris valvulis orbicularibns margiuatis, cauda brevi.ssima 

 acuta. 



Habitat in ventrienlo phocae vitnlinae. 



Rudolphi (1809, p. 135, 13G) ne.xt describes the worm as follows:

Ascaris: Capitis ralnilis orhicnlarihitis marginatia ; corpore aeiiuali, liiiea lalerali non exstante, canda 

 acuta.
