8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 95 



CARNEYELLA ULRICHI, n. sp. (Bassler and Shideler) 



Plate 6, figs. 5, 6 



Theca an elevated sack about 20 mm wide and 10 mm high, with 

 the general features of C. pUcus, but differing decidedly in the very 

 spinous surface ornamentation of the plates. In both species the 

 plates are minutely punctate, but in C. ulrichi each plate bears at least 

 one round, swollen pustule ending in a sharp, pointed spine, and the 

 larger plates have a number of such elevations all sharply marked 

 and distinct from each other. Each of the ambulacral plates bears a 

 sharp, rounded spine on the outer half and a similar elevation emerges 

 from the inner edge. The interambulacrals have one to four such 

 spines, and each of the larger elongate marginal plates sometimes 

 bears several dozen. Each of the outermost series of small plates has 

 a single spine in the center. 



This and the following new species, as well as several other species 

 herein described, were discovered by Dr. W. H. Shideler and gener- 

 ously presented to the National Museum. The writer has included 

 Dr. Shideler as coauthor of these two species, since both of us wish 

 to name them in honor, respectively, of Drs. Ulrich and Foerste, 

 whose knowledge of the edrioasteroids as well as of other groups 

 has always been at our service. 



Occurrence. — Cincinnatian (Maysville-Bellevue formation), rail- 

 road cut, south of Maysville, Kentucky. 



Holotype.—US.'nM. no. S-3964. 



CARNEYELLA FOERSTEI, n. sp. (Bassler and Shideler) 



Plate 6, figs. 7, 8 



This well marked species of the C. pileus group is similar to the 

 preceding in its general characters but differs in its more robust theca 

 and broader, longer, more developed ambulacra, and particularly in 

 the surface ornament. Each of the ambulacral plates has one to four 

 round pustules on the broad end next to the interambulacral area and 

 a single ridgelike elevation longitudinally arranged along the rest of 

 the plate. Elsewhere one to a dozen round pustules rise from each 

 of the finely punctate plates, whereas in C. ulrichi the corresponding 

 elevations are sharp-pointed spines. 



Occurrence. — Richmond (Arnheim formation), Russellville, Ohio. 



Holotypc.—V.S.^.yi. no. S-3965.
