Off Funchal (^i. M. N.), Salvages {Be Noronlia). As first described and 

 figured by Busk this species was said to be distinguished from S. scmpea by 

 the fact that it had only a single minute spine at the outer angle of the orifice : 

 but in the ' Challenger ' Report it assumes an entirely different aspect. As 

 compared with the S. scrapea of our southern coasts, it is more slender in all 

 its parts and of less porcellanous appearance. The oral opening is shorter 

 and more round in outline, with the hinder margin flattened, and sometimes 

 finely granulated ; the marginal spines are connnonly six, four on the outer 

 and two on the inner margin ; the scutum is nearly round, with its pedicel 

 attached to the middle of its side ; the lateral avicularia are of somewhat 

 larger size than in S. scrupea ; and median small avicularia often occur 

 situated by the base of the scutum. I have not seen the ocecia. 



In S. scrupea the spines are usually two or three on the outer, and one or 

 two on the inner margin of the oral aperture. The scutum is distinctly 

 reniform, and the pedicel is attached in front of the middle. My observations 

 agree with those of Hincks, who states that he has not seen frontal avicularia 

 when no ocBcia are developed, but that when ocecia are present there is usually 

 a small avicularitim seen immediately above them.

 vol. ix. 1861, p. 77, pi. 32. fig. 1. 



I have not seen any specimen exactly corresponding with Busk's figure ; 

 but with the amended characters of S. Macandrei it would certainly seem that 

 S. maderensis can scarcely be kept apart from it.
