TROPICAL PACIFIC HOLOTHURIOIDEA. 149 



nearer the latter, I refer the specimen to that species, though not without some 

 doubt. The tables have an annular disk with eight distinct spines, and a dis- 

 tinctly smaller top with twelve to twenty teeth; the rods composing the spire 

 diverge basally, not converging as in languens. 



Holothuria impatiens. 



Fistularia impatiens Forskal, 1775. Desc. Anim., p. 121. 

 Holothuria impatiens Gmelin, 1788. Syst. Nat. Linn. ed. 13, p. .3,142. 



This is another of the common wide-spread Indopacific species occurring 

 in both collections. It was taken in the Paumotu Islands at Fakarava, October 

 12, 1899, and again at Makemo, October 20. On February 3, 1905, a specimen 

 was found at Manga Reva, Paumotus, notable for its color, seal-brown with the 

 papillae cream-color. The specimens are all much contracted. Four specimens. 



Holothuria languens. 



Selenk.4., 1867. Zeits. f. w. Zool., 17, p. 335. 



This well-known Panamic species is represented in the 1904-1905 collec- 

 tion by three specimens, 15-40 mm. long, all much contracted and in poor 

 condition. Two are from Taboguilla Island, Panama, October 31, 1904, and 

 the third was collected at Perico Island, Panama, October 26, 1904. 



Holothuria leucospilota. 



Stichopus (Gymnochirota) leiicospilota Brandt, 1835. Prod, descr. Anim., p. 251. 

 Holothuria leucospilota Lampert, 1885. Die Seewalzen, p. 71. 



This species, so long known under Selenka's famiUar name, vagabunda, 

 must imquestionably bear Brandt's much earher name, though both Lampert 

 and Th^el refused to recognize such a change. Four specimens were taken 

 during the voyage of 1899-1900, the locahties being: — 



Rangiroa, Paumotus, September 21, 1899. 

 Maketea, Paumotus, October 6, 1899. 

 Fakarava, Paumotus, October 2, 1899. 

 Ponape, Caroline Islands, February 12, 1900. 



Holothuria lubrica. 



Selenka, 1867. Zeits. f, w. Zool., 17, p. 329. 



This well-known Panamic species is represented in the 1904-1905 collec- 

 tion by five specimens. There is some diversity of color but the general shade 

 is brown, darkest dorsally; in one specimen, blackish spots on the dorsal side
