4 ART. 4.— BASHFORD DEAN. 



Dot as widely distinct from the other genera as I had been led to be- 

 lieve from the work of Goode and Bean, — always granting that the spe- 

 cies raleighana and pacifica belong to the same genus, and of this we 

 cannot be sure until there can be had a better knowledge of the speci- 

 mens in Washington. I thus find that " clasping organs " are pre- 

 sent in " Harriotta " pacifica, very much as in other Chimaeroids, and 

 we are led to infer that the male specimen (49 cm.) of H. raleighana 

 was distinctly immature. But upon this again w r e cannot decide until 

 there has been a more critical examination of the type specimens. 



The notes I have collected regarding the Japanese " Harriotta " 

 are arranged as follows : 



I External Characters. 

 II Integument. 



III Skeleton (including fin structures). 



IV Viscera. 



a. Gills. 



b. Circulatory. 



c. Digestive tract and appendages. 



d. Urogenital. 



V Characters of the eç^-case. 

 VI General Considerations. 



I. Exfernal Characters. PI. I, Figs. 1, 2, 3 and 8. 



A mature specimen of a female " Harriotta " pacifica measures 

 about 120 cm. in length, and of a male about 90 cm. The specimen 

 which I dissected, a full grown female, measured over 130 cm. 



In outward appearance, " Harriotta " suggests more closely Cal- 

 lorhynchus than Chimaera. It has thus the broad, somewhat hetero- 

 cercal tail, a greatly produced snout, and fewer dermal denticles. As 

 in most chimaeroids, a distinct opisthure is present. The color in this
