Asthenosoma Reynoldsi A. Ac. n. sp. 
This species grows to a large size, measuring, when expanded, fully 9 inches in 
diameter. It is the Atlantic representative of 4. coriaceum, to which it is closely 
allied. When alive the outline of the test is globular, of an ashy gray color, with 
patches of a darker brownish or a dirty claret color, especially on the actinal side 
of the test. 
Readily distinguished from A. hystrix by the larger, higher coronal plates, the 
prominent vertical row of primary tubercles on the outer edge of the interambu- 
lacral area on the abactinal side, the less numerous secondaries and miliaries, and 
the color of the test. The primary spines, quite closely packed, on the actinal 
side are long, slender, slightly curved, and trumpet-shaped; on the abactinal 
side they form one principal vertical row extending half-way to the apical system 
near the outer edge of the interambulacral areas, The rest of the test is 
covered by distant small secondary spines.

Phormosoma Sigsbei A. Ac. n. sp. 
Closely allied to P. placenta, from which it differs in having a smaller number 
of coronal plates, a stouter test, and primary radioles on the actinal surface re- 
sembling those of P. dursaria. The color of the test when alive is of a reddish- 
orange color near the ambitus, and more pinkish towards the apical system,
