SCIENTIFIC SURVEY. -|^3j 



Alcyoneum carneum ; Pecten tenuicostatus (not plenty but prob- 

 ably more abundant further up the river;) Trochus occidentalis 

 (rare;) Natica pusilla, N. clausa. At Devil's Head, Chirodota 

 laevis (plenty) ; Mya arenaria (large and more plenty than at East- 

 port) ; Chiton marmoreus ; Tectura testudinalis ; Margarita undu- 

 lata; Buccinum undatum ; Homarus Americanus (abundant); Can- 

 cer irroratus (very rare.) 



Before leaving this section of the State I occupied some days in 

 examining the bottom in the neighborhood of Eastport, where, at 

 Shackford's Head I found some of the finest specimens which I 

 had taken during the exploration, consisting of Actinia obtruncata, 

 Bolteuia reniformis (very abundant), Velutina haliotoides, Hyas 

 coarctata and a number of crustaceans. 



A little below Todd's Head at Eastport, we found the Corymor- 

 pha nutans so abundant that they were attached to nearly every 

 mesh of the dredge net. 



At a short distance from this point, in from fifteen to forty fath- 

 oms of water I found Astrophyton Agassizii ; Solaster papposa, S. 

 endeca (plenty); Yoldia myalis (rare) ; Callista convexa ; Anatina 

 papyracia ; Cochlodesma Leana ; Thracia truncata ; Trochus occi- 

 dentalis ; Trophon clathratus ; Fasciolaria ligata. 



Dredging from Lubec to West Quoddy Head, on a hard nullipore 

 bottom, I took large numbers of Chiton marmoreus, finding them 

 attached to almost every pebble. 



I observed in this section the absence of the eel grass (Zostera 

 marina) so common in the western part of the State, its place 

 seeming to be supplied by the Chorda filum. The shores here are 

 well lined with the fuci, while in the Passamaquoddy bays the 

 Laminaria are quite small. 



My time having now nearly expired, I concluded to devote the 

 remainder to a preliminary reconnoisance of other sections of the 

 work. I accordingly embarked upon a vessel bound up the coast, 

 and visited, among other places, Machias bay, where I found, in 

 from four to seven fathoms, Actinia obtruncata, (?) (plenty); A. 

 sipunculoides, (1 specimen) ; Astarte semisulcata ; Cardita borealis ; 

 Sternaspis fossor, (very large,) and some fine forms of Polyzoa; — 

 Narraguagus bay, securing the Xucula proxima in great plenty ; — 

 Eockland harbor, taking, in five fathoms, nullipore bottom, Cuvieria 

 Fabricii, plentifully ;— Pemaquid light, near which, in thirty-five 

 fathoms, I dredged fine specimens of Corymorpha nutans ; Entails
