pair of cirri, and are a very little shorter than the rudi- 

 mentary rami of these same cirri. 



General Remarks. — Having examined this species first 

 in the genus, I fully anticipated that the very remarkable 

 character of the inner rami of the fifth and sixth cirri 

 being rudimentary, and serving the same function (if any) 

 with the caudal appendages, would have been generic ; but 

 this is not the case, for Alepas cornuta cannot be separated 

 from A. minuta without violating a clear natural affinity. 



4. Alepas Tubulosa. 



Quoy et Gaimard. Voyage de l'Astrolabe, PI. xciii, fig. 5, 1834. 



A. aperturd parvd prominente et tubulosa : scutis etpro- 

 minentiis secundum marginem carinalem, nullis. 



Orifice small, tubular, protuberant ; capitulum without 

 horny scuta or projections along the carinal margin. 



Animal unknown. 



New Zealand, Tolaga Bay. Attached to a living Palinurus. 



I have given the above brief character from the plate, 

 and imperfect description in the voyage of the Astrolabe. 

 The small and distinctly tubular orifice, and the smooth 

 carinated edge of the globose capitulum, appear suffi- 

 ciently to distinguish this species from A. cornuta. The 

 colour is stated to have been white with violet tints. 

 Length, two (French) lines.
