Station 4795. One specimen. 



The specimen is a male, measnring 40 mm. in length in contracted 

 state. No account need be added to the excellent descriptions given 

 by Mortensen and Britten. 



Habitat. — Besides the localities given by Ludwig (1900) the fol- 

 lowing may be added: Stor-Fjord, Spitzbergen; and vicinity of 

 Novaja-Semlja (Michailowskij, 1902, 1904); Nordenskjold Sea; and 

 north of New Siberia Islands (Kalischewskij, 1907); Ochotsk and 

 Japan Seas (Britten, 1907) ; east coast of Kamchatka.

Cucumaria capensis Theel, Challenger Holothurioidea, pt. 2, 1886, pp. 62-64

Cucumaria tegulata Augustin, Japanische Seewalzen, 1908, pp. 24-25, text-figs.

Cucumaria capensis, var. parva Mitsukuri, ActinoDodous Holothurioidea, 1912, 

 pp. 233-235, pi. 8, fig. 74, text-fig. 45. 



Station 4900. Four specimens. 

 Station 4903. One specimen. 



The largest specimen is only 10 mm. long. The Japanese speci- 

 mens reported on under the above-mentioned names by Augustin and 

 Mitsukuri are doubtless identical with Theel's. As Ludwig had only 

 a small specimen, 15 mm. long, under observation, I can not follow 

 Mitsukuri in separating the Japanese form as a variety. 



Habitat.— Off Cape of Good Hope (Theel, 1886) ; Cape Town (Ludwig, 

 1887);. Moro Strait; southwest of Timor; and Sulu Archipelago 

 (Sluiter, 1901); Uraga Channel (Augustin, 1908); Jogashima and 

 Moroiso, Misaki (Mitsukuri, 1912); off Goto Islands, west of Kyushu.
