Nearly one half of the above are found at much lower points 

 in the western part of the State, and there, generally, not above 

 the laminarian region. 



In the vicinity of the same locality, in from ten to twenty-five 

 fathoms of water, the dredge brought up — Alcyonium carneum ; 

 Actinia obtruncata ; Astrophyton Agassizii ; Ohiopholis scolo- 

 pendrica; Cribella oculata ; Solaster papposa, S. endeca ; Echinus 

 granulatus ; Pentacta frondosa ; Gemellaria dumosa ; Ascidia cal- 

 losa ; Cynthia pyriformis; Boltenia reniformis(?) ; Terebratulina 

 septentrionalis ; Pecten tenuicostatus (rare ;) Nuculadelphinodonta; 

 Yoldia sapotilla, Y. myalis ; Modiolaria discors, M. corrugata ; 

 Cryptodon Gouldii, x\starte semisulcata, Cardita borealis, Lyonsia 

 hyalina. Pandora trilineata ; Chiton marmoreus, Chiton albus ; En- 

 talis striolata ; Crucibulum striatum ; Cemoria noachina ; Scalaria 

 groenlandica ; Lunatia triseriata ; Nassa trivittata ; Buccinum un- 

 datum ; Fusus pygmffius, F. decemcostatus, F. islandicus ; Sipun- 

 culus Bernhardus ; Sternaspis fossor. 



After exploring this region as thoroughly as the time and weath- 

 er wonld permit, we made a hurried visit to Cobscook river. At 

 Pembroke Point we collected numerous fine specimens of fossils 

 of marine animals, but in consequence of the strong tide which here 

 flows with great velocity, it was impossible to use the dredge. 



Proceeding thence to Perry, we visited, on the way, the fossil 

 deposits on Upper Treat's Island, where we procured some speci- 

 mens, mostly Lingulae. 



At Little river in Perry, a small collection of Devonian fossils 

 rewarded our labors. 



Returning to Treat's Island we resumed dredging, for a few 

 days, with satisfactory results, and thence, Mr. Packard having left 

 me, I turned my attention to the exploration of the St. Croix river, 

 dredging between Devil's Head and Robbinston. In the vicinity of 

 St. Croix Island the dredging in seventeen fathoms of water was 

 productive of good results. The following are some of the speci- 

 mens collected here :
