A\'itli the fact that Luidia maculaia ah\a3-s lias more than five arms justifies 

 the coudusioii that Liddia maculata M.T. ^'ar. quinaria v. Martens is a 

 distinct species. 



It was then descriljed very fully by Sladen under the name of Luidia 

 h'mhcda [ '89, p. 251] : 



" Luidia Jimhatn, n. sp. (PI. XLIY, figs. 3 and 4 ; PI. XLV. figs 7 and 

 8). 



"Kays five. E = 110mm., r=15 mm. E = 7.3 r. Breadth of a ray near 

 tlie base, at the broadest pai-t, 18 mm. 



" Kays moderately long, verj^ flat, and rather broad, tapering sloAvly 

 from base to the extremity, wliich is not very attenuate ; frequently with a 

 slight lateral constriction at the base. Abactinal and actinal smiaces 

 Rul)plane, bevelled towards the margin, wliich is subangular, slightly rounded. 



" The jD^^ll«^ of the abactinal area are large, compact, closely fitting, 

 and square, excejat along the median radial Hne and the centre of the disk. 

 The larger paxilla3 bear on the tabulum about a dozen, or even more, low, 

 hemispherical gi'anules, subequal, comparatively Large and well-spaced, and 

 roimd the margin a series of very small, short, cilia-like spinelets, about 

 two dozen or more in number, the series often appearing to be double. 

 There are thi'ee to fom* regular longitudinal series of square paxillee at the 

 sides of the ray. In the intermediate area along the median radial line 

 the j)axillcTe are smaller, and have a tendency (more marked in some ex- 

 amples than in others) to become rounded or irregular in form. 



" The paxiUse, wliich represent the aborted suporo-margiual x^l'^^es, are 

 remarkal)le for bearing on their tabulum a broad, low, valvular pedicellaria 

 resembling the form frequently found in Pentagonasteridse. These pedicel- 

 laria are most numerous in the ueighbom-hood of the interbrachial 

 arcs, and ma}- there extend upon the adjacent one or two series of lon- 

 gitudinal paxilla?. Along the ray, however, they are generally confined to the 

 outermost or * suj)ero-marginal ' series. Sometimes on the inner jmrt of the 

 ra}' there are two x>ecli<?öllari8G on one tabulum ; but toAvards the extremity 

 of the ray veiy few are pi-esent at aU. Karel}' a pedicellaria may be com- 

 l)osed of three valves, as in some Pentagonasterida?, the valvate character of
