2-6 crossbeams. The shape of these tables is also subject to a rather 

 wide range of individual variation. Elongated tables in caudal 

 appendage 150-330/f in length, anal teeth bOO/i long and 150/m broad. 

 Phosphatic corpuscles are uniformly distributed in young specimens, 

 while in older ones they are aggregated into patches of about 300/i in 

 diameter. 



Habitat. J up An (v. Marenzeller, 1881); Sagami Sea (Theel. 1SS6: 

 Augustin. 1908; Mitsukuri, 1912): off Echizen. Honshu: Kagoshima 

 Bay: Suruga Bay.

Station 5039. Eive specimens. 



All the specimens are large, total length of body being 100-125 mm. 

 Color uniformly grayish-purple. As unfortunately the deposits had 

 been totally dissolved when the specimens were ex am i T ied by me. my 

 observations were made on a single preparation mounted by the late 

 Professor Mitsukuri, and are imperfect. Scattered tables of perisome 

 measure 60-1 Ooii in diameter, while those in caudal appendage are 

 110-230/.!, spire 80a high. Except in the oral and caudal parts, skin 

 thickly beset with phosphatic corpuscles, not unfrequently exceeding 

 160 a in diameter. 



Habitat. — Gulf of Panama (Ludwig, 1894); Gulf of California 

 (Ludwig, 1594; Clark, 1913); numerous stations along the Pacific 

 coast of Xorth America (Clark, 1907; : orT Hitaka, south of Hokkaido.

Station 5030. Seven specimens. 

 The largest specimen is 70 mm . long. All these specimens lack 

 phosphatic corpuscles completely. Anchors and rosettes of racket- 

 shaped bodies are also wanting. The characteristic spindle-shaped 

 deposits of general perisome measure 0.63-1.55 mm. in length, aver-
