part of the plate is interpreted as the medianmost of the marginal 

 series. In each maxiliary plate aboul 26 tritors are present, far less 

 distinct, however, than in the other plates. Of these tritors all bul 

 one arc marginal, and in tin's row the mosl conspicuous arc the third 

 and fourth, counting from the symphysial region and also the 

 twentieth or thereabouts. The mosl conspicuous tritor of all is the 

 one which occurs on the inner .surface of the plate. 



An examination of the viscera of this species has shown hut

Characters of the Egg Case. 



Two specimens of the egg ease of this form are preserved in the 

 Imperial University of Tokyo and two in Columbia University. The 

 fifth specimen, referred to by Günther (Ann. & Mag. Nat. Hist. 4 (6.) 

 L889, [». 415), is probably preserved in the British Museum. Its 

 general size and character are well shown in the accompanying il- 

 ilustration, PL I, Fig. 3. In point of size (length about 27 cm.) 

 it is notably larger than those of other members of this genus. It 

 approaches most closely to that of C. monstrosa, as figured, for 

 example, by Grieg (1898, Bergen s Museums Aarbog. No. 3. p. 15.) I 

 notice, however, that the web like margin in the egg case oi the 

 Japanese species is much the narrower, and is lacking in conspicuous 

 striation. On the other hand, the texture of the shell shows con- 

 spicuous longitudinal striae. In its form, too, the elongated narrow 

 end of the egg case is proportionally narrower and shorter. The 

 character of the opening end of the case is closely similar in both 

 species, bul the perforations occurring near the extreme tip oi the 

 narrow end of the egg case are finer and more numerous in the 

 Japanese species. The color of the case when freshly deposited is a 

 flee}) shade of Indian yellow. I have observed that two eggs are
