ends, nearly 3 times as long as the width of the body ; apical tuber- 

 cle indistinct.

3. Linckia Brownii, Rumph. Amb. t. 13. f. E ? Seba, Mus. iii. t. 6. 

 f. 13, 14. Grew, Mus. t. 8. f. 1, 2 ? Rays elongate, cylindrical, rather 

 tapering at the end, 4 times as long as the width of the body ; back 

 of the arms with 3 or 4 rows of small tubercles ; sides with 4 rows 

 of large pierced spots ; apical tubercle moderate. 



Inhab. New Holland. Rob. Brown, Esq. 



4. Linckia Leachii. Rays elongate, slender, cylindrical, rather 

 tapering ; sides with 3 or 4 rows of rather convex tubercles ; apical 

 tubercle indistinct ? 



Inhab. " Isle of France." Dr. W. E. Leach. 



Very like L. Typus. Our specimens, which are almost all young of 

 the Comet variety, are only to be distinguished from that species by 

 the arms being slenderer. The adult may differ more. 



5. Linckia Guildingii. Brown, olive varied ; rays slender, elongate, 

 cylindrical, nearly equal, largely granular ; back and sides with 

 groups of 3 or 4 holes between the interspaces of the tubercles, api- 

 cal tubercles large and convex. Monstrosity 6 -rayed. 



Inhab. St. Vincent's. Rev . L. Guilding. 



Differs from L. Typus principally in being much smaller and slen- 

 derer. 



6. Linckia pacifica. Rays elongate, cylindrical, rather tapering 

 at the end, 6 times as long as the width of the body, with close 

 oblong convex ossicula, apical tubercle indistinct ; the series of spines 

 near the ambulacra crowded together with them. 



Inhab. Tahiti on the reefs. H. Cuming, Esq. 



7. Linckia Columbia. Rays elongate, cylindrical, rather tapering 

 at the end, covered with large coarse granulations ; series of spines 

 very close to the ambulacral spines, oblong and truncated. Mon- 

 strosity, with 1 of the rays long, rest small, reproduced. 



Inhab. West coast of Columbia. H. Cuming, Esq. 



\\ Rays 5, rather trigonal, with 1 or 2 continued bands of pores 

 without any intervening tubercles on each side. Phataria. 



8. Linckia unifascialis . Rays trigonal, tapering ; back with 3 

 rows of flat ossicula ; sides with a single broad band of pores ; 

 rather more than 3 times as long as broad. 



Inhab. Bay of Caraccas, West Columbia, on the rocks at low water. 

 H. Cuming, Esq. 



9. Linckia bifascialis. Rays trigonal ; back with 4 or 5 rows of 

 irregular convex ossicula at the base, and many at the end of the 

 ray, sides of the ray with 2 broad bands of pores at the base and 1 

 at the end. 



\\\ Rays depressed, with a single pore between each dorsal ossicule, 

 and a narrow band of a few pores along each side of the arm. Acalia. 



10. Linckia pulchella. Brown, rays flat, nearly 3 times as long
