248 VERRILL 



The dorsal surface of this species is closely covered with smaller 

 pseudopaxillae, having finer and more numerous spinules, than in any 

 other west American species, except S. galaxides, in which they are 

 still smaller. 



It is allied to S. stimpsoni Verrill, from the Northwest coast of 

 America; S. subarcuatus Sladen, from the Southern Indian Ocean, 

 S. lat. 52 04', in 150 fathoms; and S. torulatus Sladen, from north 

 of the Kermadec Islands, in 250 fathoms. 



TERATOLOGY. 



A medium-sized specimen, taken at Eastport, Maine, has ten rays, 

 but one of the rays forks beyond the edge of the disk, the two forks 

 becoming like the other rays, in size and form, distally, so that it 

 becomes eleven-rayed. Otherwise it has the ordinary characters of 

 the species. 



Specimens with nine rays and twelve rays are not very rare. 

 Those with ten rays are about as common as those with eleven rays.

This is a broad-disked species, usually with nine or ten rays, cov- 

 ered above with very small, flat-topped, crowded pseudopaxillae, and 

 resembling 5. endeca in form and color. The two type specimens 

 have nine rays. The larger has the radii 40 mm. and no mm.; 

 ratio, about i : 2.7. It was orange-color in life. 



The marginal spines are about as in 5*. endeca, but the inferomar- 

 ginals are more elongated transversely, and bear a decidedly greater 

 number of more minute spinules. 



The peractinal series of pseudopaxillae extends only to about the 

 basal third of the free part of the ray. They are relatively smaller 

 than in endeca, being here only about half the size of the infero- 

 marginals proximally. 



The actinal interradial areas are apparently relatively larger than 

 in endeca of the same size and number of rays, and bear a larger 

 number of compressed pseudopaxillae, the larger ones similar to the 

 inferomarginals and peractinal s. They form about sixteen radial 

 rows, the smaller one in the median rows distally. They are cov- 

 ered with a large number of small, rather short, regular spinules.
