ties of L. buccata. Its occurrence here and at Saco is interesting, as showing that this 

 locality was at the northern limits of the Acadian fauna of the Quaternary period. 



Yoldia pygmcea Minister. [Kucula lenticula Moll.) I have compared the fossils with the 

 recent shell from Greenland labelled " lenticula Mciller," received through the kindness of 

 Dr. C. Liitken of Copenhagen, and find no differences between them. It is not uncommon 

 both here and at Saco. From Mr. C. B. Fuller. 



Mytilus cdulis Linn. Very abundant in the higher levels of the clays associated with 

 Euryeclrinus drobachiensis and Serripes gronlandicus. In a higher bed in another part of the 

 city occurs a beach deposit formed largely, according to Mr. Fuller, of the comminuted 

 angular fragments of this species, and among them occurred a valve of Pholus crispata 

 Linn., now in the collection of Mr. C. B. Fuller of Portland, who has discovered most of 

 the forms here enumerated. 



Astarte compressa Linn. (Not A. comprcssa Montagu, Forbes, and Hanley ; A. clliptica 

 Brown.) Common. Morse, Fuller. 



Astarte Banksii Leach. Abundant. Forms closely resembling, if not identical with, 

 specimens of A. Lawrentiana received from Dr. Dawson show that the latter is but a 

 variety. 



Astarte striata Leach. Not infrequent ; associated as usual with the preceding species. 



Astarte lactca Brocl. et Sowb., Gould ! Rare. (Fuller.) 



Cardium Ilayesii Stimps. Rare. Fuller. 



Serripes gronlandicus Beck. Abundant in what must have been the bottom of a much 

 shallower estuary than the species is now known to inhabit. On the coast of Labrador it 

 abounds in muddy bays, ten fathoms deep. 



Mactra poly nana Stimps., Smith. Misc. Coll., no description. (M. ovalis Gould.) Not un- 

 common at Zeb's Cove, Cape Elizabeth. 1 



Macoma sabulosa Spgl. In the usual abundance, though not so much so as in the Labra- 

 dor deposits. 



Solen ensis Linn. Collection of Mr. Fuller. 



Mya arenaria Linn. Abundant. 



Mya truncata Linn. Common. 



Saxicava arctica Desh. Common. 



Pholas crispala Linn. Rare. 



Margarita cinerea Gould. Rarely found. 



Natica affinis Gmel. (TV. clausa Brod. et Sowb.) Frequent. 



Naiica {Lunatia) gronlandica Beck. Frequent. 



Natica (Amaurojms) islandica Gmel. (iV. helicoidcs Johnst.) Coll. Portland Nat. Hist. Soc. 



Buccinum undulatum Mciller. (B. labradorense Reeve.) 



Buccinum plectrum var. Packardi Stimps. Can. Nat., Oct. 1865. 



Dr. Stimpson quotes his typical recent specimens from near Behring's Straits, where they 

 " were dredged alive in twenty to thirty fathoms, in the Arctic Ocean north of Behring's 

 Straits, by Capt. John Rodgers, U. S. N." 



Buccinum Tottcni Stimps., Can. Nat., 1865. Frequent. 



Buccinum gronkindicum Hancock. Frequent. Specimens in the Collection of Mr. Fuller 

 agree well with Lyell's figure of " B. angulosimi," a synonym of this species. 



Buccinum crctaceum Reeve. Pack., Can. Nat. and Geol., Dec. 1863, pi. ii., fig. 6.
