In one sample I saw a form. which I think must be referred 
to this species. ;

The specimens observed differed from the quoted figure by 
Daday in being somewhat more lengthened.

This species varies much in length and shape of its inferior 
end. Some of the specimens observed may be referred to the form 
figured by Daday 1. c., Pl. 19, f. 9, being longer and more 
cylindrical than usually in northern specimens. Thus they approach ig 
to T. Lobiancoi Daday. l. c., p. 553, Pl. 19, f. 27 but none of my 
specimens was so long as figured by Daday 1..c. Pl. 19, f. 27.

house. I name it in memory of my fellow-traveller, Dr. Th. Mor-
