Fishes of the Western North Atlantic 551 



KnowL, JO, 189;: 32; also, Mem. Harv. Mus. comp. Zool., 22, 1896: 32; type species, H. raleighana 

 Goode and Bean. Continental slope of northeastern United States, between offings of Virginia and New 

 Jersey, 707-1,081 fathoms. 



Generic Synonym: 



Anteliochimaera Tanaka, J. Coll. Sci. Tokyo, 27 (8), 1909: 7; type and only included species, A. chaetirhamphus 

 Tanaka; Japan. i'- 



Generic Characters. No separate anal fin. Upper margin of caudal fin without 

 denticles. Dental plates with more or less prominent grinding ridges and knobs (tritors). 

 Characters otherwise those of the family. 



Range. Long-nosed chimaeroids, referable to Harriotta by the smoothness of the 

 upper margin of the caudal, by the nature of the dental plates, and by the absence of 

 a separate anal fin, are known only from the continental slope off the middle Atlantic 

 States and off Nova Scotia in the western Atlantic; near the Canaries and west of 

 Scotland in the eastern Atlantic; from Japan; probably also off Lower California. 



Species. H. raleighana Goode and Bean 1895 from the two sides of the North 

 Atlantic and H. chaetirhamphus (Tanaka) 1 909 of Japan resemble one another so closely 

 that they have been united recently under the older of these two names. "^ Since we have 

 not seen any Japanese specimens, we are not in a position to judge whether they are in 

 fact identical. The rhinochimaerid described from off Lower California by Townsend 

 and Nichols"^ as H. curtis-jamesi also resembles H. raleighana so closely that the illustra- 

 tion of it does not suggest any significant difference. But the nature of its dental plates 

 is not known in detail. And an empty egg capsule from the Bay of Bengal, reported as 

 Callorhynchus(^}), seems rather to have belonged to some rhinochimaeroid, perhaps 

 to Harriotta (p. 550, footnote loi).

Study Material. Juvenile male, about 485 mm long to posterior rays of upper side 

 of caudal fin, from continental slope off Virginia at 781 fathoms, Albatross St. 273 

 (Oct. 25, 1886), in U. S. National Museum; also three maturing males, 535-558 mm 

 to upper origin of caudal, and one newly hatched female, 1 12 mm, trawled on the con- 

 tinental slope off southern Nova Scotia and on the southeastern slope of Georges Bank 

 at 400—460 fathoms,^*'^ in Harvard Museum of Comparative Zoology; an empty egg 

 capsule, probably of this species, from off southern New England, Lat. 39° 47' N, 

 Long. 70° 31' W, at 963 fathoms, Albatross St. 2216 (August 22, 1884), in U. S. 



102. Referred here to Harriotta rather than to Rhinochimaera because the upper anterior dental plates and also the lower 

 plates are described (we have not seen it) as having ridges (tritors), the latter also with grinding prominences.

 64°oo' W, 440—450 fath., trawled by the research vessel Caryn in July 1949.
