 Rah. Unia Islands, north of East Crete (Spratt). 

 The form of the neck and the apparatus claustralis heing nearly 

 identical, this shell must he considered a local variety of C. scidp- 

 ticollis, though its colour and habitus are indeed very different from 

 those of the shell inhabiting the neighbouring Sofrana Islands.

 Hab. Near Kandia (town), island of Crete (Spratt). 

 One of the Admiral's most interesting species, and without close 

 relation to any other known Alhinaria. The neck-crests being ana- 

 logous in form to those of G. sculptieollis, I think best to rank it 

 here next to that species. But the habit also approaches somewhat 

 that of C. olivieri, Roth ; and so the new shell seems to connect the 

 olivieri with the ccerulea group. Accordingly I prefer to place it in a 

 group by itself in the vicinity of the ccerulea group.

Hab. Kavallos Islands, east of Crete (Spratt). 



This species, which I name in honour of Rear-Admiral Arthur 



Lucis jNIansell, who for many years served in the Levant under Vice- 



Admiral Spratt (see Spratt's ' Travels and Researches in Crete ') and 



now resides at Chalkis, is nearly allied to C. clara, Bttg., from the 



Bay of Mirabello ; but the ribs of its shell are nearly equidistant aud
