CLA.T7SILIA. 337 



breadth 7*6 min. and, except in being rather weatherworn, it 

 completely resembles the latter. Dr. Clarke informs me that 

 the second Gouldian specimen is almost exactly like the one 

 sent, except that it is a trifle shorter and stouter, measuring 

 24 x 8 mm., the last whorl especially being proportionately shorter 

 and less contracted, although there is very little difference in the 

 apertures. I have taken the opportunity of giving an illustration 

 of Gould's shell. 



Fig. 116. Clausilia vespa . 

 (From one of Gould's original specimens.) 



I am unable to follow Mr. Sykes when he states that C. vespa 

 must be removed from the Oospira section, for in spite of the 

 fact that in establishing this section Blanford described the apex 

 as very blunt, and that vespa has the apex rather acute, the whole 

 aspect and consistency of the shell of vespa resemble those of 

 the other members of the group to such an extent that I prefer to 

 retain it as a member of the section, abnormal only in the apex.
