No. 4.] CHALMERS — SURFACE GEOLOGY. 203 



B. glaciale, Linn. 



B. undatunij Linn ; frequent. 



Tritonofusus Kroyeri., Muller. 



Fusus tornatus, Gould. 



Balanus crenatus, Brug ; very abundant. 



B. Ilameri Ascan ; rare. 



In the Jacquet River beds the remains of a small cetacean 

 were discovered about 25 feet above sea level in a clay cutting 

 of the Intercolonial Railway. Nearly the whole skeleton was 

 obtained which was sent to Halifax and identified by Drs. Gilpin 

 and Honeyman as that of Beluga Vermontana, Thompson. In 

 the Tattagouche clays, Rev. C. H. Paisley found Eurychinus Dro- 

 bachiejisis, Muller (^Echimis granulatus) ^ two species of *S/>iVo?'- 

 his and remains of the eel grass, Zostera marina L. and of 

 Equiseta in addition to the above. And during the past sum- 

 mer I discovered a portion of the claw of a lobster (^Homarus 

 Americanus Edw.) at Black Point, Restigouche County, in a 

 situation which made me almost certain it was in the fossil 

 state, as it was embedded in a heap of clay washed out of the 

 side of a railway cut and associated with fossil shells of Saxicava 

 rugosa, Mya arenaria, M. truncata var. Uddevallensis, etc. 

 The specimen has a battered, worn appearance too, and looks as 

 if it might be as old tis the shells, neverthelcvss until others shall 

 have been found, I would not care to make any positive asser- 

 tions about it. 



The fossils in the Leda clays of this district are all remark- 

 ably well preserved, and many of them occur apparently in their 

 natural situation, especially in the lower clays ; but, from the man- 

 ner in which they are distributed, deep water and littoral species 

 often appearing intermingled in the same beds, their value, as 

 indicative of the depth of water in which they lived, is not to be 

 greatly relied on. Nevertheless some deductions may be drawn 

 from them regarding the climate and temperature of the seas at 

 that period. At Charlo River the shells occur in blue clay, 

 below high-water mark, and a majority of the species are arctic. 

 They probably lived in waters of moderate depth. Balanus 

 crenatus and Saxlcava rugosa are the most abundant forms, but 

 Leda pernula, Trltonofusus Kroyeri, Nucula tenuis are also fre- 

 quent, especially the last, while Portlandia glacialis is rare. 

 The two first mentioned species (^Balanus crenatus and Saxi- 

 cava rugosa) must have found a congenial habitat in these seas
