RECHE-DE-MER FISHERIES. 237 



on each side ; tactile suckers abundant throughout the dorsal region ; colour, cream, or light 

 stone-colour, with golden-brown patches or mottlings of various shapes and dimensions, through- 

 out the dorsal and lateral surfaces, no two individuals being marked precisely alike; tactile 

 suckers and tentacles, light brown ; length eight to twelve inches ; not abundant. Of small 

 commercial value. 



11. Grey-fish, or Grey Sand-fish, Holotliuria fnsco-ciiicrea. — Body elongate-ovate or sub- 

 cylindrical, somewhat depressed, very slightly flexible, corrugated transversely when contracted ; 

 locomotive acetabula sparsely and irregularly scattered along the ventral surface ; slender tactile 

 papillae similarly developed on the dorsal aspect ; vent funicular, subcylindrical, its free edge 

 fimbriate ; colour varying from light to dark ashen-grey, the ventral region of similar colour, or 

 only slightly lighter, short irregular transverse blackish bands, to the number of ten or twelve, 

 commonly present on the dorsal surface ; oral tentacles light grey or buff. Length in extension 

 ten to fifteen inches. Habitat : Common on sandy shores and reefs exposed by the ordinary 

 tides. Of little commercial value, owing to the abundance of spicules developed in the integu- 

 ment, which impart to it, when cured, a distinctly chalky aspect and consistence. 



12. White-fish, or White Sand-fish, Holothnria cdnlis. — Closely resembling the last species, 

 but with a simple, non-funicular, ventral aperture, and nearly pure white beneath. Of small 

 commercial value, owing to the abundance of spicular elements. 



13. Brown Sand-fish, Holothnria impaticiis. — Closely resembling Holothnria cdnlis, but of 

 a light brown hue throughout. Of small commercial value. 



14. Spotted or Leopard-fish, Holothnria argns (Chromo XIL, Fig. 7). — Body in extension 

 elongate-ovate, rounded at each extremity, its surface smooth ; ground colour, lilac, diversified 

 with oval or rounded golden-brown spots which are usually partly disposed in longitudinal 

 chain-like series, and partly irregularly scattered throughout the dorsal and lateral surfaces, no 

 two individuals being precisely alike in this respect; each golden-brown spot contains a 

 centrally-located, dark brown, tactile acetabulum, and its circumference is defined by an inner 

 dark brown and an outer pure white line ; oral tentacles light brown. Length twelve to 

 eighteen inches. Emits cotton-like, Cuvierian filaments very plentifully. Abundant on the 

 reefs at ordinary low tides. Of little commercial value, but sometimes mixed with the better 

 kinds. 



15. Large Lolly-fish, Holothnria vagabnnda. — Body in extension elongate cylindrical, its 

 surface conspicuously corrugated. Intense velvety black throughout, with the exception of a thin 

 red or orange line around the aperture of the vent ; oral tentacles and ventral and tactile pedicels, 

 black; the terminal acetabula of the latter grey. Abundant on the outlying reefs of the Barrier 

 system. Of low commercial value. 



16. Small Lolly-fish, Holothnria saiigninolciita, n.sp. (Plate XXXIV., No. i ). — Body in exten- 

 sion elongate subcylindrical, tapering towards each extremity, highly flexible ; locomotive acetabula
