ASTEROIDEA OF NORTH PACIFIC AND ADJACENT WATERS— FISHER 147 



sleeves of tissure and wreaths of pedicellariae surrounding the abactinal spines, 

 abactinal straight pedicellariae predominantly the large spatulate unguiculate sort 

 (the lanceolate being also present, but fewer than in biordinata); the rays are not 

 nearly so deciduous as in the northern formae. 



This is probably a subtidal (littoral) form only, for in deep water in Monterey 

 Bay is a slender spined variant of forma loelleri (pi. 70, fig. 1) with which it undoubt- 

 edly intcrgrades over rocky bottom. 



As mentioned under "Variations," the Monterey form has a large proportion of 

 the superomnrginals spine bearing, and as the dorsolateral area is narrow the abactinal 

 spines appear close set. The wreaths of pedicellariae frequently touch. 



In this form the inner marginal mouth spine is rather long, slender, blunt, or 

 truncate. I have never observed it to be short and broad as is sometimes the case 

 in forma Tcoehleri. 



This is not a regular "low-tide" species but is found only at the lowest tides 

 of the year and apparently wanders inshore from subtidal regions, in very rocky 

 situations. 



Type (forma montereyensis).— No. E. 1428, U.S.N. M.
