are noted. The PyramideUidce. includes the genera Odostomia 

 with the new sub-genera Odostomella and Farthenina, Turbon- 

 illa, Eulimdla^ Eulima with sub-genus Lelostraca and Menestho. 



Sixteen species of Odostomia are noticed, of which three 

 are described as new — O. Monterosatoi, O. Penchynati, and 

 O. Jeffrey si, the last also with a \zx\ety flexicosta. 



The execution of the plates continues to be very satisfac- 

 tory ; the photographs of the minute species are however not 

 made from the objects themselves, but from enlarged drawings.

Limnasa peregra v. Burnetti Alder. — This variety of 

 Limncea peregra is more local than rare, as it occurs plentifully 

 where it is to be found, the only known localities being Loch 

 Skene, in Dumfriesshire, and a small lake in Breconshire. There 

 is a peculiar interest attached to it, living as it does in lakes 

 among mountains. I have had opportunity of observing it 

 only at Loch Skene where it lives and thrives on ' the rude 

 barriers of the lake ' in company with two kinds of trout, the 

 ordinary burn trout and a trout quite peculiar to this Loch, the 

 flesh being red and the fish of singular beauty. The Limncea 

 evidently delights in the Scotch summer mists, for when I 

 visited the Loch one of the mists fell heavily, hiding the moun- 

 tain, and then it was I secured my finest specimens, these 

 creeping up rapidly from the bottom of the loch to the top of 

 the rocks, where I easily secured them. In sunny weather 

 they appear to be more sluggish, attaching themselves chiefly to 

 the sides of the rocks or resting at the bottom of the loch. 

 Loch Skene is a wild spot, but beautiful in its wildness, charm- 

 ing to the lovers of geology as it reposes among the old Silurian 

 rocks with their grits, graywackes, and lower Silurian shales. 

 Also to the botanist the district has its delights, for here grow 

 among the mosses at its sides the cloudberry {Pubiis chamce- 

 moriis), and the cranberry ( Vaccinium oxycoccus), and many 

 other interesting plants. Limncea peregra v. Bur7ietti led me
