in all the others it is divided in varying degrees at tip (fig. B), and in 

 one extreme case the division is carried half way down the whole 

 length of the papilla (fig. A). Ovarian ova 2.5 mm. in diameter. 

 Deposits are exactly the same as those described and figured by 

 Ludwig for his E. tanneri, except that I could not find any stunted 

 bodies in genital organ. 



Ludwig's specimen seems to belong to the same species as the two 

 original specimens of Theel, secured from off the coast of Chile and 

 rather imperfectly reported. Since the size and shape of dorsal papil- 

 lae are very variable, I am convinced that the Atlantic forms, E. eor- 

 nuta Verrill, E. depressa, var. minor Theel, E. auriculata Perrier, 



Fig. 1.— Euphronides depressa. Dorsal unpaired papilla from various individuals, showing 



variation in degree of bifurcation. xl 



E. violacea Perrier, and E. talismani Perrier are identical with one 

 another. 



Habitat— Oft the coast of Chile (Theel, 1882); north of Cape San 

 Francisco (Ludwig, 1893); south of Totomi, Honshu. 



Genus BENTHODYTES Theel. 



37. BENTHODYTES SANGUINOLENTA Th6el. 



Benthodytes sanguinolenta Theel, Challenger Holothurioidea, pt. 1, 1882, pp. 104- 

 105, pi. 23; pi. 40, figs. 4, 5; pi. 42, fig. 6. — Ludwig, Albatross Holothurioidea, 

 1894, pp. 53-60, pi. 1, figs. 1-8. 



Station 4971. Four specimens. 



Station 4972. One specimen. 



Station 4973. Five specimens. 

 To the excellent description given by Ludwig a few additions may 

 be made. Sparsely scattered rods are found not only in walls of 

 tentacles and genital tubes but also in the intestinal blood vessels. 

 These deposits are similar in shape to those in other parts, measur- 

 ing 150-250/x in length. In the largest specimen, 210 mm. long, the 

 coecal appendage of cloaca measured 40 mm. long and 6 mm. across, 

 with its apex divided into two branches about 5 mm. long. The 

 large ovarian ova measure 2.2 mm. in diameter, as stated by Ludwig. 

 Habitat. — Off the coast of Chile (Theel, 1882); Panamic region 

 (Ludwig, 1894); Lower California (Clark, 1913); Bengal Bay (Walsh, 

 1891); Laccadives and Andaman Islands (Koehler and Vaney, 1905); 

 off Kii, Honshu, Japan.
