H0LOTHUB.IA RUGOSA Ludwig. (Plate LIII. fig. 4.) 



Holothuna ruqosa H. Ludwig, Arb. zool.-zoot. Inst, in Wiirzb. 

 Bd. ii. 1875, p. 110, Taf. vii. fig. 33. 



Distribution. Eecorded from Samoa, Pelevv Is., New Britain, 

 Waigeoe Island. 



One specimen from Kotuma, 125 mm. X 22 mm., tentacular crown 

 small (11 mm. in diameter). The five longitudinal furrows 

 mentioned by Ludwig visible but not conspicuous, body flesh- 

 coloured. 



Deposits exactly as described and figured by Ludwig, but, as in 

 the specimens described by Theel (p. 226), tables with more than 4 

 vertical supports to spire were exceptional.

In spite of Prof. Ludwig's separation of H. subclitiva Selenka 

 from U. pardalis Selenka, after Sluiter's examination of a large 

 number of specimens from the Bay of Batavia all the evidence 

 seems to point to the advisability of regarding them as one species, 

 a view which has been upheld by Theel (as well as Sluiter). 



Distribution. This species occurs all over the Indo-Pacific region 

 from Zanzibar to Cocos Is., as well as in the East American littoral 

 region (Surinam and Florida ?). Prof. Ludwig (1887, Z. c. p. 1242) 

 described 2 specimens from Falkland Is., which would extend the 

 range of the species into the Antarctic littoral region, but in 1898 

 (Z. c.) he expresses some doubt as to the correctness of the locality 

 recorded. 



Several specimens from outer reef and mangrove swamp 

 Funafuti : largest is 79 mm. x 10 mm., diameter of tentacular 

 crown 7 mm. when expanded; another specimen 39 mm. x 9 mm., 

 tentacular crown expanded 4-5 mm. in diameter; 20 tentacles 

 (counted in 2 specimens). The specimens vary in colour in the 

 way described by Sluiter. The buttons are very frequently in- 

 complete and in those individuals examined they were irregularly 

 distributed as in H. subclitiva ; the tables have, as a rule, a reduced 

 spire, and their discs, which are invariably spinous, vary in size from 

 •07 mm. to -04 mm. in diameter ; curved rib-like rods occurred (as 

 described) in the dorsal feet only.
