did not give any reason for tliis procedure, either. Without attaching too great importance 

 to these statements — the writers in question obviously did not possess any very profound 

 knowledge of the systematic value of the different characters in tliis genus — I wish to point 

 out that the length of the frontal organ in the above-mentioned species of Th. Scott's, 

 especially in the female, (cf. loc. cit. pi. XV, fig. 33) agrees very much better with the 

 corres])onding organ in E. Chierchiae, re-described by me above, than with E. aculeata, 

 G. \V. MlJLLEK, 19U6a. The shape of the shell, too, (see Th. ScOTT, 1894, pi. XV, 

 figs. 5 and 6), seems to favour the view of the two first-mentioned writers more than that of 

 G. W. MtJLLER. But on account of the incompleteness in the description given by Th. Scott 

 it did not seem convenient to include the name Halocyfris aculeata in the list of synonyms 

 worked out above.
