STARFISHES OF THE PHILIPPINE SEAS. 



329 



J\ Inferomarginals with small lateral spines, at least in tlie interbrachial arc. 

 &. Proximally 2 or 3 subambulacral spines, or prominent pedicellariae ; 



abactinal pedicellariae cristatns Sladen, p. 329. 



c'. Proximally 1 prominent subambulacral spine ; no abactinal pedicellariae, 



sarissa Alcock. 

 6*. Inferomarginals witbout lateral spines. 



c*. Pedicellariae only on the adambulacral plates ; abactinal granules few 

 and microscopic, visible only when abactinal membrane is dried; the 

 abactinal area has superficially the appearance of being without 



granules epixanthus Fisher. 



c*. Pedicellariae on the abactinal and actinal intermediate areas, as well as 

 on the adambulacral plates; abactinal granules numerous, at least in 

 center of disk, and easily seen wthout a magnifier. 

 d\ Superomarginals decreasing regularly and gradually in length from 

 the first ; granules distributed uniformly all over abactinal area, 

 e". R=2 r ; central granules of each abactinal plate the largest ; prox- 

 imal superomarginal plates coarsely granulated all over; supero- 

 marginals all wider than long granulosus Fisher, p. 333. 



e*. R=2.6 r ; granules smaller, uniform ; superomarginals finely granu- 

 lated, only a few proximals with coarse central granules ; supero- 

 marginals at middle of ray longer than wide. 



rugulosus Fisher, p. 338. 

 d". Superomarginals maintaining their width to near end of ray ; gran- 

 ules numerous in center of disk, becoming much smaller and more 

 widely spaced as periphery is approached ; superomarginals of 

 proximal half of ray with coarse central granules. 



Uthosorus Fisher, p. 336.

Notes on Philippine specimens. — The large series of specimens 

 dredged by the Albatros represents all stages from the young to the 

 adult, while the latter exhibit considerable range of variation, par- 

 ticularly in the number and form of the pedicellariae. 



The change in proportions due to increasing age is shown by th& 

 following table, the measurements being in millimeters : 



The last two specimens are larger than Sladen's type.
