by spinelets which are little more tlian elongate papillae ; they are small, 

 stimapy, covered with membrane, rather widely spaced, and usually no definite 

 order of aiTangement is discernible, although about two irregular rows may 

 be traced in some insttmces. 



" The spinelets on the actinal intermadiate plates are similar in character 

 and disposition to the foregoing, and tliey merge imperceptibly into the 

 squamules of the infero-marginal plates. This uniformity in the dermal 

 appendages imparts a characteristic appearance to the actinal aspect of the 

 starfish. 



" Tlie mouth-plates are elongate, each with two short, flattened, truncate 

 spinelets at the inner extremity, followed by about six pairs of short robust 

 spinelets, wliich stand perpendicular on the surface of the x^l^-^ö, and form 

 two series apposed to one another ; these are succeeded by about four rather 

 broader, shorter, and more robust spinelets, forming a single series in 

 continuation, as it were, of the two apposed series, on the outer extremity 

 of the plate, towards wliich the spinelets decreasa as they proceed outward. 

 Consequent on tliis method of arrangement there is a marked division of 

 the mouth-plate armatm*e into two narrow series separated by the median 

 suture hne of each mouth-angle. 



" The madreporiform body is small, and situated at alx)ut one-tliird of 

 the distance from the margin to the centre of the disk. 



"The terminal (ocular) plate, thougli small, is conspicuous and elong- 

 ately oblong. 



" Colom- in alcohol, umber-brown, becoming lighter in shade towards the 

 extremities of the rays. The spinelets are white. Small specimens are 

 yellowish white. 



" Young pJicise. — ^A small example, Avhich lias a major radial measm'e- 

 ment of 16.5 mm., may readily be distinguished as belonging to the species. 

 It is to be noted, however, that tlie paxillae of the abactinal area have 

 qiute a different cliaracter, tlie s^^inelets of the crown being long, and 

 radiating nearly horizontally. The armatiu'e of the adambulacral plates and 

 mouth-plates is comparatively longer, especially on the latter ; and on the 

 actinal sm'face of the adambulacral plates behind tlie fmTow series there are
