Family ASTROPECTINID^. 

 ANTHOSTICTE, new genus. 



Near Tethyaster but distinguished by the presence of very deep 

 marginal fascioles, the absence of a regular midradial series of enlarged 

 paxilla?, the extension of the gonads to end of ray, and the character 

 of the paxilla?, winch are tall and slender. Superomarginal plates with- 

 out specialized spines; inferomarginals with a single transverse row of 

 small flattened, sharp, appressed spines; fascioles between marginals 

 very deep, lined with small spinelets and in continuation of the actinal 

 fasciolar channels. Ab actinal plates stellate, the shaft of paxilla 

 tall, slender, and crowned by a floriform group of slender spinelets; 

 papula? all over abactinal surface. Actinal intermediate plates 

 extending nearly to end of ray, and traversed, between marginals and 

 adambulacrals, by deep channels; no enlarged actinal intermediate 

 spines. Adambulacral plates with a very prominent furrow angle 

 and an astropectinoid armature; no enlarged subambulacral on distal 

 portion ray; fascioles between the plates shallow and not lined with 

 spinelets, as in Sideriaster. Tufts of gonads extending to end of ray. 

 Madreporic body not concealed. Superambulacral plates large. Tube 

 feet pointed, with simple rod-like deposits at tip. Small spiniform 

 abactinal pedicellaria?. 



Type. — Anihosticte aulophora, new species. 



ANTHOSTICTE AULOPHORA, new species. 



Rays 5. R = 162 mm., r=34 mm., R = 4.76 + f; breadth of ray at 

 base, 40 mm., at tenth superomarginal, 29 mm. Disk moderate, 

 rays long, rathwr narrow beyond interbrachium, tapering gradually 

 to a bluntly pointed extremity. Abactinal surface covered with tall, 

 slender-pediceled paxilla? springing from a 6-lobed (stellate) plate, 

 these without definite order on center of disk and midradial region, 

 but elsewhere in oblique transverse rows parallel to interradius. On 

 the ray these series are slightly spaced, and consecutive plates of a 

 row barely touch. In the midradial area the plates sometimes touch 

 or are separated. Summit of pedicel crowned by a floriform group of 

 15 to 20 peripheral, and 5 to 15 or even more central, terete blunt 

 spinelets, the latter often in a compact group resembling a pedicel- 

 larian apparatus, the former radiating like the rays of a composite 

 flower. On most of the paxilla? 2 to 4 central spinelets are slightly 

 modified with broader tips, and form actual pedicellaria?. Papula?
