Additions to Catalogue of Shells. 27 



classed with 'pallens, you will note several differences. In yours the 

 lateral areas are more raised, and the growth lines are strongly in 

 evidence, which is not the case with /;a/Ze«s. The angle of the an- 

 terior valve in yours is not quite the same; yours shows a slight 

 bulge towards the apex. While the anterior valve in yours is short, 

 it is barely as proportionately short as in />a?Ze?!s, but it certainly 

 has a short anterior valve so characteristic of 2MUens. The pos- 

 terior valve does not show the niucro far back on a long valve, but 

 that may be due to its damaged condition. Yours suggests a little 

 more carination, but this may also be due to damage. In conclusion 

 I should place your shell with ])olle>is/'' 



Mr. Ashby kindly sent us his only co-type for comparison. We 

 quite agree with his remarks. Our specimen is not quite half the 

 length of the co-type. We have not yet found I. juloides on ou)- 

 coast.
