188 GERITHIADJi. 



is very narrow, greatly produced, and terminates in a par- 

 ticularly acute point that slopes dorsally (or upwards) ; it 

 runs perpendicularly downwards, and indeed is a mere 

 prolongation of the anterior extremity of the body. Upon 

 the thickened inner side of the lip (which is otherwise per- 

 fectly smooth) profound grooves mark the diverging course 

 of the external keels ; the throat and pillar are devoid of 

 any sculpture, save a laterally compressed longitudinal pad 

 upon the latter opposite to the two Inferior belts of nodules. 

 There is a slight but rather diffused inflection of the mar- 

 gin of the outer lip at the commencement of the caudal 

 j)rocess. 



Our native examples, which were thin, yet apparently 

 fully formed, at most measured an inch and a quarter in 

 length, and a fifth less for the extreme breadth between the 

 point of the second digitation, and the edge of the whorl 

 immediately opposite to it. A foreign individual vied with 

 pes-pelecani in length and surpassed it in breadth. 



This fine species was dredged in seventy, ninety, and one 

 hundred fathoms off the east coast of Zetland (M'Andrew). 

 It has since been taken in the same district by Mr. Barlee. 



A, PEs-PELECANi, Linuseus. 



Spire, if anything, longer than the body : digitations usually 

 four, short and broad ; the caudal one stunted, and a little 

 dilated, its point leaning veutrally or downwards.
