Lepty chaster anotnalus Fisher. 



The first description of this species is due to Fisher and is as follows 

 [ : 06a, p. 115 ] : 



"Kays 5. R = 27mm. ; r=17mm. ; R=1.6 r. Breadth of ray at base, 

 19 mm. 



" In general form and ornamentation greatly resembling Parastropeden 

 inermis Ludwig. Disk broad, rajs short, broad and blimt ; interbracliial arcs 

 shallow and wide ; abactinal smiace subplane, capable of shght inflation ; 

 marginal plates conspicuous, devoid of enlarged spines or spinelets, but 

 covered with granules and granuhform spinelets ; actinal intermediate areas 

 broad ; adambulacral plates with 3 or 4 furrow spines ; small superambulacral 

 plates present; a very tiny anal pore present. 



" Abactinal paxillar area compact ; paxillae arranged in not very regular 

 obhque ti-ansverse rows at sides of ray ; without order in median radial 

 areas and centre of disk. PaxiUa3 largest at base of ray and in interradial 

 areas decreasing conspicuously in size toward centre of disk and tip of ray ; 

 large at sides of paxiUar area than in mid-radial region. PaxiUge with 

 subcircular bases liaving 5 or 6 very shoii iiTegular lobes, by which neighbom- 

 ing plates touch, or even imbricate in centi'e of disk and mid-radial area. 

 Papulae in 5's and 6's (except in centre of disk and along mid-radial lines 

 where they are absent). Column of paxiUse about as liigh as breadth of 

 base, flaring at siunmit, the largest crowned with a coordinate floriform
