1. Body pentagonal ; the dorsal ossicula lunate, nairow; 

 the edge of the arms acute. 



1. Patiria coccinea. Scarlet, the body 5-rayed, sides 

 concave, the end of the rays rather slender, blunt. Gray,

2. Body 5-7-ayed; rays thick, rounded; dorsal ossicula 

 lunate, subtriangular ; arms convex above and rounded 

 on the sides. 



2. Patiria grariifera. Brown. Back rather convex. 

 The anns broad, rovmded at the end, nearly as long as the 

 diameter of the disk, rounded above, flat beneath ; the 

 lunate dorsal ossicula covered with short, crowded spines, 

 and with only a few small tufts of spines between them ; 

 the ossicula of the oral surface each with a transverse line 

 of six or eight spines. Gray, P. Z. S. 1847, p. 82. Aste-

Variety. The arms more slender, about one-third longer 

 than the diameter of the disk. Inhab. ? (Brit. Mus.) . 



The variety may be a distinct species ; but the specimen 

 is not in sufficiently good preservation to determine this 

 point with certainty. 



3. The body 5-rayed, rays thick, rou7ided ; the dorsal ossi- 

 cula, especially those at the end of the arms, broad, 

 rounded; the back covered with two or three beaked 

 pedicellaria nearly hiding the tubercles. 



3. Patiria ocellifera. Body 5-rayed; arms thick, rounded, 

 as long as the diameter of the disk, bhintish at the end ; 

 the dorsal ossicula Ijroad, oblong or roundish, reddish, 

 covered with short, crowded spines ; the oral surface with 

 transverse rows of three to five mobile spines. Gray,

This species much more nearly resembles Oudart 's figure 

 than the species I have described under the name of Nec- 

 tria oculifera. 



4. Patiria obtusa. Brown, depressed, 5- to 6-rayed ; rays 

 depressed, rounded at the end; dorsal surface with lunate 

 ossicula crowded with short spines ; oral surface with 

 circular groups of crowded spines in the middle of each 

 ossiculum. Gray, P. Z. S. 1847, p. 82. Inhab. Panama. 

 Sandy mud, 6 to 10 fathoms. 



5. Patiria'? crassa. Pale yellow (dry), 5-rayed; rays 

 tliick, rather tapering, about half as long again as the 

 diameter of the disk. Dorsal sm-face formed of convex, 



B. Ambulacral spines radiating, webbed together. 



VI. Pteraster. Ambulacra edged with a series of 

 radiating, webbed spines. Pteraster, jNIiill. & Trosch. Ast. 

 App. 127, 1843.

2. Pteraster Capensis. Body subpentagoual, swollen, edge 

 very thick, rounded ; back convex, reticulated, with rounded 

 groups of very small ossicula at the junction of the reti- 

 culations. Gray, P. Z. S. 1847, p. 82. Inhab. Cape of 

 Good Hope. 



The spines of the ambulacra are like those of Pteraster 

 miliai-is, but they arc longer, and the series of webbed 

 spines on their outer margins are scarcely longer than those 

 of the ambulacra, while in the northern species thej^ are 

 much longer and thicker, and there is no appearance ol 

 the two long glassy spines at the angle of the mouth so 

 distinct and peculiar in that species. 



VII. Ganeria. Body flat, 5-rayed. Back coriaceous, 

 strengthened with numerous small, linear and curved series 

 of very short cylindrical spines . Margin perpendicular, with 

 two series of narrow ossicula, each armed w'ith a central, 

 erect linear series of short cylindrical spines. Oral surface 

 covered with diverging spines, one being placed on each 

 ossiculum. Ambulacra linear, with two seri^s-^j^^yj^icles, ' 

 and edged with sujttilate spines, t^pff.on cach'ossJ^^i^*uil 

 with a series of diverging spines "^t the an^cs near 

 mouth. Gray, P. Z. S. 1847, p. 83. 



1. Ganeria Falklandica. Body 5-rayed; rays as long as 

 the diameter of the disk, rather blunt at the tip. Gray, 

 P. Z. S. 1847, p. 83. Inhab. Falkland Islands {Captain Sir 

 James Ross) . 



VIII. SocoMiA. The body depressed; rays elongate 

 formed of imbricate plates ; the margins broad, the upper 

 and lower series of ossicula being separated bv a groove.
