SPECIES DUBIiE. 



of L. anatifera; and that A. hirsiita bears a similar re- 

 lation to L. anserifera. In Lamarck's ' Animaux sans 

 Vertebres/ Pollicipes villosus of Sowerby is quite incor- 

 rectly given as a synonym to the above A. vittosa.

This, I think, is certainly a distinct and new species, 

 but I am unable to decide whether to place it in Lepas or 

 Paecilasma. It is briefly described and pretty well figured 

 in the above work. It was procured at New Zealand, 

 but it is not stated to what object it was attached. The 

 capitulum is much elongated, and one inch in length; 

 the peduncle is from six to eight lines long. The carina 

 is said to be very narrow ; it is not stated whether it 

 terminates downwards in a fork or disc ; judging from 

 the figure, it extends some way up between the terga, 

 the basal ends of which are bluntly pointed. The scuta 

 are almost quadrilateral. The peduncle is short, yellow, 

 and tuberculated. The general appearance of the drawing 

 makes me suspect that it is a Paecilasma.

Leach has most briefly characterised a specimen in 

 Savigny's Museum, from the Red Sea, under the above 

 name of Clyptra. It has only four valves, and its peduncle 

 is smooth; by the latter character it is distinguished from 

 lbla. Apparently this is a distinct and new genus. 



Mr. J. E. Gray, in 'Proc. Zoolog. Soc./ 1848, p. 44, 

 quotes a description by Stroem (' Nym. Saml. Danske,' 

 1788, 295, n. hi, f. 20), namely, " Lepas testa compressd 

 1-valvis, stipite lamellosd." It is found attached to
