ELIOT: NTJDIBKANCHIATA FROM CAPE VEED ISLANDS. 155 



there is always one low denticle in the middle which divides them into 

 two halves. On either side of this median denticle are 30-45 longer 

 ones. They are fairly regular and straight. 



No essential differences could be found between these specimens and 

 those marked B. The latter are smaller (the largest 5 mm. long 

 and 3 bi'oad), but have larger and more inflated cerata. The radula of 

 the specimen dissected consisted of 11 teeth, which had somewhat fewer 

 denticles on each side (25-30), and were perhaps bent into a somewhat 

 narrower arch. 



All the specimens of both sets are white, as preserved, and I think 

 all can be referred to Spurilla neapolitana. They are probably 

 immature, for the species attains a length of about 4 cm. in the 

 Mediterranean, and, this being so, one cannot be sure that they 

 represent distinct colour varieties in the adult. It would appear from 

 Vayssiere's figure of one of the cerata (I.e., 9«), that they are covered 

 with minute, white dots, as in these specimens. 



Amphorina PALLIDA, n.sp. PL XIV, Fig. 11. 



Only one specimen preserved. Mr. Crossland's notes are as follows: — 



"^olid. 26/7/04. 



"On a stone which was coated with Spirorbis. In these sur- 

 roundings, not visible to the naked eye, but this probably an accidental 

 circumstance. 



"Elongated, but foot is as broad as the ventral surface. No pedal 

 tentacles. Oral tentacles rather thick and blunt, about half as long 

 as the rhinophores. Latter not perfoliated and (like the cerata) blunt 

 and thick at the tip. Whole dorsal surface and its appendages snowed 

 over with pure white pigment, the brown liver only showing at the 

 narrowed bases of the cerata. There is, besides, a pair of clear areas 

 above the eyes, postero-laterally to the rhinophores. Ring composed 

 of bright orange-i-ed dots, half way up the rhinophores, and the oral 

 tentacles have a similar colour, less definitely arranged. Foot ends in 

 a long slender transparent tail. Cerata in four sets, of which the 

 third is the largest and contains the longest cerata. Each set consists 

 of but two cerata. The first pair have three or four red specks 

 anteriorly." 



The preserved specimen is white, 3'5mm. long, and stoutly built. 

 There are only two cerata in each of the four rows. They are 

 inflated, and the largest are about 1"5 mm. high. The other external 

 characters correspond with the description of the living animal. 



The jaws are very thin, and hardly visible. I could not make out 

 any denticles on the masticatory edge. The radula consists of a single 

 row of about 80 teeth. As in Amphorina c(Brulea (see Yayssiere, I.e.), 

 the teeth are of diiferent sizes, about 35 being large and 45 small. 

 They are of the horseshoe shape, but somewhat asymmetrical. They 

 bear a strong median denticle, which rises rather far back, and 

 three lateral denticles only, on each side (Fig. 11). 



No stylet or chitinous tube could be discovered on the penis, but its 

 absence cannot be regarded as certain. 



This specimen is perhaps immature, but it seems to be sufficiently
