THE GIANT TRILOBITE OF MoosE RIvEeR [RON Mine, N. S. 
ATTENTION has again been directed to this interesting 
crustacean. 
From a correspondence with Prof. Vogdes, of Fort Hamil- 
ton, New York, the Trilobite which we considered a new species 
and named Asaphus ditmarsie, seems to have been the first of 
the family in Nova Scotia to which special attention has been 
given. It is now over half a century since it was described 
figured and named. Prof V. has kindly sent me the following 
description, which is sufficiently convincing and very interest-

A tolerably perfect fragment of the abdomen and tail of this 
highly interesting fossil comprised all of the animal which has 
yet been found. Eleven articulations of the middle lobe, and 
ten of the lateral lobes are quite distinct. All the costal arches 
or ribs are smooth and rounded, being without pustulatizes 
strie or grooves. Four of the upper arches of the dorsal, or 
middle lobe are longer than those on the sides of the body, a 
peculiarity which is sufficiently decisive to mark the species. 
Indeed this organization furnishes a striking exception to the 
generic characters of the Asaphus, as given by Professor Brong-
