The branches of the dorsal aorta are stouter than in specimens 

 of Chimaera of a similar size. And the length of the branches 

 supplying the digestive tract is notably greater. The con us arteriosus 

 presents two rows of valves, approximately equal in size. Four 

 valves are present in the anterior row, and three in the posterior. In 

 addition to these, several rudimentary valves are situated in the folds 

 of the conus near its opening into the heart. 



C. Digestive Tract and Appendages. PI. II, Fig. 9. 



The gut is narrower in calibre and proportionally longer than in 

 other Chimaeroids examined. The spiral valve completes four turnes. 

 The liver is bilobed, and is somewhat smaller than in Chimaera. If 

 one recalls the sectorial dental plates in this form and the absence of 

 tritoral areas it is interesting to findthat the gut contained débris of 

 small fishes, and was altogether lacking 1 in the remains of hard shelled 

 forms, crustacean or molluscan. 



D. Urogenital System. PJ. II, Figs. 9 and 10. 



The oviducts differ little from those of Chimaera. They are 

 more conspicuous in that they lie unpigmented (ocd.) against the black 

 dorsal wall of the body cavity. Minor differences include the shape 

 of the capsular gland which in surface view [»resents a Y-shaped 

 appearance on account of the mode of grouping of its lamellae. In 

 the specimen dissected, a single external opening was present for both 

 oviducts (tt-'J.)- I am, however, inclined to regard this as a condition 

 of artifact, since L have seen a somewhat similar appearance in polyor
