Sertularia pumila Linné. Ver., Inv. V.S., p. 782, 1874. 
Very common, and growing principally on fucus, on piles of wharves; 
also on floating fucus in the harbor. A very robust variety was col- 
lected from fucus stranded on the outer beach at Race Point. 
DESCRIPTION OF A NEW SPECIES OF RAY (RAKFA STELLULATA) 
FROM MONTEREY, CALIFORNIA. 
By DAVID S. JORDAN and CHARLES H. GILBERT. 
Raia stellulata sp. nov. 
Allied to Raia 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 interocular 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 
prickles 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 very sharp, tricuspid, about 
“30 to 40 
Sot, 
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 markings sharp and distinct. Numerous black spots of all sizes, 
some of them ocellated. A black spot about as large as the eye at the 
Nasal flaps slightly fringed externally. Distance between
