Sertularia pumila Linnd. Vcr. , luv. V. S. , p. 732, 1874. 



Very common, and growing principally on fucus, on i)iles of wharves; 

 also on floating fucus in the harbor. A very robust variety was col- 

 lected from fiicus stranded on the outer beach at Eace Point. 



DESCRIPTION OF A NEW SPECIES OF KAY (RAIA STEIiliUtiATA) 

 FBOITI ITIONTEREir, CAr.IFORNIA. 



By DAVID S. JORDA]\ and CHAKLES II. OILBERT. 



Raia stellulata sp. nov. 



Allied to Baia radula Delaroche. Disk much broader than long, 

 anteriorly broadly arched, and convex, the tip of the snout very slightly 

 exserted. Anterior margin of pectorals undulated, convex anteriorly, 

 then concave. Length of snout from eyes a little more than twice the 

 width of the interocidar space, which is concave, less than the distance 

 between the outer angles of the spiracles. Breadth of disk equal to the 

 distance from the tip of the tail to the shoulder-girdle. Length of tail 

 equal to the distance from its root to the middle of the interocular area. 



Male everywhere above rough with stellate prickles, the base of the 

 pectorals being almost smooth. Along the middle region of the back 

 and the whole upper surface of the tail is a band of close-set, rather 

 low prickles, with broad, very distinctly stellate bases. An elongate 

 patch of stout, recurved spines on the anterior part of the pectorals, 

 and farther back the usual series of claw-like spines found in the males 

 of all species. Stout spines above the eye, a few in the middle of the 

 shoulder, and along the middle line of the tail. Sides of the tail with- 

 out large prickles. Lower side smooth, except around the mouth. 



Female everywhere above rough with stellate prickles, the anterior 

 region, middle of back, and upper surface of tail most so. A median 

 row of strong spines on the tail above, and six on the scapular region. 

 A series of strong spines over the eye. A lateral row of rather strong 

 jjrickles on the tail. Body smooth below, except anteriorly. 



Tail flat below, with a conspicuous lateral fold. Dorsal fins low, their 

 height equal to the interorbital space, separated by a space considerably 

 shorter than their base. Caudal fin reduced to a very small fold, as in 

 the "genus" Uraptera^ to which this species would be referred in Miiller 

 & Henle's arrangement. 



Mouth somewhat arched. Teeth not A'ery sharp, tricuspid, about 



— ^ — Nasal flaps slightly fringed externally. Distance between 



nostrils about equal to the distance from them to the tip of the snout. 

 Color grayish-brown, everywhere mottled with light and dark colors, 

 the markiugs sharp and distinct. Numerous black spots of all sizes, 

 some of them ocellated. A black spot about as large as the eye at the
