DESCRIPTION OF A NEW TRILOBITE.

important question, and at the same time to report the examina- 

 mination of other localities from various parts of the Province. 

 In conclusion, I will only say, that specimens of alga?, 

 especially of lighter kinds from the shores of the Bay 

 of Fundy, or Gulf of St. Lawrence, would be highly prized by 

 me, if any members have the means of obtaining them, and could 

 not fail to furnish much that would be new and interesting in the 

 study of our Microscopic Flora. 



Note. — Harris' Cove is about thirteen miles from the outlet of Ken- 

 nebeckasis Bay, and three miles from its head. As the streams which 

 enter this arm of the lake at the mouth of the Saint John River, are all 

 of small size, the salt water which flows inward at flood-tide over the 

 Falls, or rapids connecting it with the harbour, has free access to 

 the locality where those organisms were obtained. 



The water is not so brackish however, as to prevent the growth of 

 Potamogeton perfoliatus, Potamogeton pectinatus, Nuphar lutea, con- 

 fervse and other aquatic plants ; which by their luxuriant growth choke 

 the shallow waters of this and other coves in Kennebeckasis Bay, and 

 are frequently uncovered during the low stage of the river, at midsum- 

 mer. During the freshets of early spring the salt water is for a 

 time completely excluded by the floods poured into this lake-like expan- 

 sion of the river, by the main St. John.

Fig. I. — 0. Logani. The anterior point of glabella in this figure 

 is slightly too narrow. 



Fig. II. — An imperfect specimen shewing the hypostoma in
