3, ALEPAS CORNUTA. PI. Ill, fig. 6. 



A. aperturd parvd, leviter prominente : scutis nidlis : 

 capitulo plerumque tribus, parvis, conipressis eminetitiis 

 secundum carinalem margin em instructo. 



Orifice small, slightly protuberant ; capitulum without 

 horny scuta ; generally with three small flattened pro- 

 jections along the carinal margin. 



Outer maxillae with the inner bristles divided into two 

 groups ; segments of the posterior cirri extremely nu- 

 merous, each with one pair of main spines ; inner rami 

 of the fifth and sixth cirri rudimentary. 



St. Vincent's, West Indies, attached to an Antipathes, collected by the 

 Rev. L. Guilding. 



Capitulum globular, slightly flattened, smooth, trans- 

 lucent, entirely destitute of valves ; orifice slightly pro- 

 jecting or tubular, parallel to the longitudinal axis of the 

 peduncle, with the edges sinuous ; it appears more tubular 

 than it really is, from the convexity of the part of the 

 capitulum immediately beneath the orifice. Three small, 

 flexible, horny, irregular prominences project from the 

 carinal margin ; one at the bottom of the capitulum ; a 

 second about half-way up it ; and a third generally close 

 to the orifice ; but their positions vary a little, and the 

 prominences vary still more in shape and size, being 

 either rounded and very small, or much flattened and 

 considerably prominent ; they are imperforate ; in the 

 membrane under them a few tubuli may be seen, which 

 are not elsewhere visible ; their summits are roughened 

 with very minute points and beads of chitine ; others, 

 still minuter, are scattered over the whole capitulum. 



Peduncle short, narrower than the capitulum, into 

 which it insensibly blends ; strongly wrinkled ; surface of 

 attachment wide ; position with respect to the branches 

 of the coralline, various.
