taken at random , was found to be 42 cm., and of one hundred females 

 41 cm. In general the largest males are more abundant than the 

 largest females. The average number of eggs in the species is com- 

 puted to be eighteen (in 400 individuals). The length of the egg 

 at the time of spawning measures about 22 mm. not including the 

 terminal filaments. An opercular ring is occasionally present at the 

 vegetal pole. The anchor filaments are more numerous than in any 

 known myxinoid, 100 or more being often present. 



The egg of this species is shown in PI. I. Fig. 7, and may be 

 compared with those of other Japanese myxinoids figured in the same 

 plate. In Text-figure 1 is shown the pattern formed by the bases of 

 the anchor filaments in the case of four eggs selected at random : at 

 the vegetal pole (A, B, C, D) the number of filaments varies between 

 91 and 72, at the animal pole (E, F, G, H) between 119 and 67. 

 The average of ten specimens examined is 79 and 88 respectively 

 Surrounding the micropylar funnel the first ring of filaments is made 

 up of eight (average) components and they are situated close to the 

 micropyle. 



As far as the chances of obtaining embryonic material is con- 

 cerned, I have no doubt that a determined effort would procure eggs 

 in the neighborhood of Misaki as readily as on the Californian coast. 

 And I may add that while absent from Misaki during the late fall, 

 specimens were secured for me which yielded eggs in the same 

 manner as those obtained in California. On that occasion more than 

 a score of eggs were taken from the slime enclosing a captured hag. 

 It is probable that some of these eggs, if not the majority of them, 

 had first been in the fishes' gut.
