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

 tical with the form described by Rudolphi in 1802, as defined by Schneider in 1866, It 

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



Historical review. — Eudolphi (1802, pp. 14, 15) was evidently the first to 

 describe Ascaris osculata; his article is not at our disposal at present. The following 

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

 following short diagnosis, taken from Rudolphi: 



Osculata Fusar. capiti8 corpore augastioris valvulia orbicularihus marginatlSj cauda brevissima 

 acuta. 



Habitat in ventricnlo phocae vitulinae. 



Rudolphi (1809, p. 135, 136) next describes the worm as follows:

 acuta.
