ANNOTATED LIST. 181 
Holothuria pardalis. 
Selenka. 1867. Zeit. f. w. Zool., 17, p. 336, pl. xix, fig. 85. 
This common species was also taken by Semon near Thursday Island, while we found 
it at Friday Island, Erub, and Mer, and even at Green Island, Queensland. It has a very 
wide range, from Zanzibar to Cocos Island, Mexico, and from Japan to Port Mackay, 
Queensland. It occurs in sand under rock-fragments. Bell (1884) records one specimen of 
H. lineata from Thursday Island and also, ‘‘with considerable doubt,’’ a single specimen of 
H. peregrina from the same place. It seems to be generally agreed now that these two 
supposed species are simply forms of pardalis. 
Holothuria pervicax. 
Selenka. 1867. Zeit. f. w. Zool., 17, p. 327, pl. xviii, fig. 54. 
(Plate 19, Figure 2.) 
This is another of the widespread Indo-Pacific holothurians, known from the Red Sea 
and Zanzibar to Tahiti and Hawaii and northward to Misaki, Japan. We found a number 
of specimens at Erub, and at Mer it is one of the commonest holothurians. It is found 
under rocks and coral fragments. The largest specimens are upwards of 300 mm. in length. 
The thick white Cuvier’s organs are normally very well developed but are sometimes scanty. 
Holothuria remollescens. 
Lampert. 1885. Die Seewalzen, p. 242, figs. 8, 9, 22. 
We found at Mer, on the under side of a rock-fragment, a dull purplish-gray holo- 
thurian, about 135 mm. in length, which seems to represent this little-known species, 
originally described from the Red Sea and since recorded only once, a single small specimen 
from Grand Coco Island. 
Holothuria rugosa. 
Ludwig. 1874. Arb. Zool-zoot. Inst. Wiirzburg, 2, p. 110, pl. vii, figs. 33a-c. 
This is another little-known species, of which we found one specimen at Mer. The 
type locality is Samoa, and the species has also been reported from the Andaman Islands, 
the Pelew Islands, Rotuma, New Britain, and Waigeu. The single individual taken at 
Mer was buried in sand under a rock-fragment on the southeastern reef-flat. 
Holothuria scabra. 
Jaeger. 1833. De Hol., p. 23—Semper. 1868. Holothurien, pl. xix. 
This big species ranges along the whole East African coast from Port Natal to the 
Red Sea and thence eastward to the Caroline and Fiji Islands; on the north it reaches the 
Riu Kiu Islands and on the south Torres Strait. It is widely used for béche-de-mer, some 
individuals making ‘‘curry-fish,” while others only rank as ‘“‘sand-fish.” Saville Kent 
(1893) does not mention scabra, and it is possible that it does not occur along the Great 
Barrier Reef. We did not find it at Mer, but we took two specimens on the sand-flat 
southwest of Friday Island. One of these was about 375 mm. long and 100 mm. thick; 
“‘white below; pale gray above finely speckled with blackish, most thickly along the mid- 
dorsal line; dorsal pedicels blackish.’’ The other specimen was smaller; ‘‘white below; 
cream-color blotched with brown above; dorsal pedicels tipped with brown.” These 
descriptions, when compared with Semper’s figure and Mitsukuri’s (1912) color notes, 
show that in the matter of its patterns and shades, scabra is quite variable.
