REPORT ON THE GASTEROPODA. 



505 



This is the smallest Gasteropod I have ever seen. Of course in the case of an Aclis, whose 

 outer lip has always a more or less unfinished look, it is difficult to say positively whether a solitary 

 specimen, which is all I have had in this case to represent the species, is full-grown or not, but I 

 am sure from the whole aspect of the shell that it is either full-grown or very nearly so. That being 

 the case, I felt that so excessively minute a creature ought to receive formal recognition.

The tip of the apex in Eulima is so characteristic, that I felt it was desirable to supply the 

 measurement of this part in each of the new species ; but it is obvious that such a measurement, when 

 taken in profile, cannot be satisfactory, because of the uncertainty as to the 



aspect under which the observer has viewed it. I have therefore given the "^jj/ & 



breadth of the first whorl as seen from a point in the line of the axis, EvXima, tip of theaheU, act; 

 reckoning for the first whorl here, as in all other cases, the part cut off by straight line? r d °&! Breadth 

 the line d I, in which case the breadth is of course the distance from a to c. at the ^ whor1, ° c -
