nel, and gradually and regularly tapers to its termination, which is 
near the end of the body. The lateral lobes are rounded. The 
costal arches of the abdomen have a furrow scooped out of their up- 
per surface, and their outward extremities terminate in obtuse points, 
between which there is a raised line. The caudal arches are not 
grooved, but there is a faint impressed line running along their up- 
per surface, which is slightly bifurcated at their termination. 
This beautiful and highly interesting trilobite was found by Mr. 
George L. Le Row, of Poughkeepsie, N. Y., to whose kindness I 
owe this opportunity of describing it. The specific name is given 
in compliment to the discoverer. There is a strong analogy in some 
leading particulars between this species and our C. Diops. Pro- — 
fessor Dalman’s C. Concinna represented on his first plate, fig. 5, a 
4 and c, comes very near it, but there are many marked differences 
between them. Mr. Le Row ina letter to me states, “ the locality 
of this trilobite is just out of the village of Fly creek, three miles 
from Cooperstown, in Otsego town and county, N. Y., on the land 
of a Mr. Williams. No other specimen has been found there. : 
possess the body of one of the same species obtained about hall 
mile from the above locality.” In the Poughkeepsie Telegraph, 
Nov. 22d, 1837, Mr. Le Row has given a figure of our trilobite, ac- 
companied by the following remarks: ‘The above specimen of a 
trilobite was obtained during the past summer, about three miles 
south of the head waters of the Susquehannah river ; it is peculiarly 
perfect, and the engraving exhibits the outlines of the fossil in a re- 
markably distinct manner.”* It was found imbedded in a layer of 
soft argillite, slightly ferruginous, and of such is the fossil composed. 
The strata in which it was found was filled with orthocere and numer- 
ous other fossils. Immediately under this layer is another of argil- 
lite, of harder texture and darker color, and free from petrifactions.
