Trehouart, publie sous la direction de Mr. Paul Gaimard. Mineralogie 

 et Geologie, par E. Eobert. 1840. — P. 283, " Les coquilles fossiles de 

 Husavik Hallbjarnastadarkambur sont d'une abondance extreme 

 dans ce terrain, et admirablement conservees, ce sont d'apres Mr. 

 Desbayes, qui a constate leur identite avec celles qui vivent encore 

 dans ces memes lieux, notamment les Cyprina Islandica, Mya arenaria, 

 Tellina solidula {T. ovata, Sowb. ?), Tellina tenuis (probably T. cal- 

 carea, Cb.), Natica clausa, Cardium voisin de ciliatum, Solen vagina, 

 S. ensis ? Buccinum voisin de Buc. reticulatum." It is stated tbat the 

 great specimens of Cyprina contain chambers filled with a blackish 

 matter, probably being part of the animal (perhaps the stomach). 

 " Avl dessus de ce gissement, les coquilles sont entassees pele mele 

 comme dans un falun ; le tufa se divise alors en plaque et renferment 

 principalement des petites bivalves." Mr. Eobert figures as Cyprina 

 Gaimardi a shell which Mr. Deshayes considers a very inflated variety 

 of Cyprina Islandica, L. 



4. G. G. Winkler. Island der Ban seiner Gebirge und dessen 

 geologische Bedeutung. Miinchen, 1863, — The fossils of Hallb- 

 jarnarstadir are for the first time stated to belong to the Crag-forma- 

 tion. Twenty-seven species are enumerated. Through the favour 

 of the author, I have received some sketches of the new species, 

 which enable me to give the following observations : — Tapes virginea, 

 Forb., is Tellina calcarea, Ch, ; Astarte Hjaltalini, Winkl., is, as the 

 the author himself supposes, A. crebricosta, Forb. ; Natica Steens- 

 trupiana, Winkl., is Natica aperta, Loven. ; Planorbis spirorhis, 

 Miill.,^ is probably mis-written for Spirorhis borealis, Daudin ; 

 Patella Itevis, Winkl., appears not to differ from Patella pellucida, L., 

 Cyrtodaria Heerii, Winkl., is perhaps G. angustata, Nyst. The fol- 

 lowing true Crag-fossils are named: — Gjprina rustica, Sowb.; Tellina 

 ovata, Sowb. ; Corbulomya complanata, Sowb. ; Cyrtodaria siliqua, 

 Spgl. ; Natica varians, Duj. ; Natica hemiclausa, Sowb. ; N. occlusa, 

 Wood, At p. 211 the following species are named as occurring at 

 Fossvogur, which may be considered of a more recent period : — 

 Mya truncata, L. ; Buccinum imdatum, L., var. vulgatum ; Balanus, sp. ; 

 Tellina, sp. From Arnabauli, p. 212, which appears to belong to the 

 same period : — Cyprina Islandica, L. ; Astarte borealis, Chem. ; Mya 

 truncata, L. ; PJiolas crispata, L. ; Pecten Islandicus, L. ; Buccinum 

 undatum, L., var. vulgatum.

 bygnad. (Kgl. svenska vetenskaps Akademiens Handlingar. 7 Band. 

 1867. Stockholm.) At p. 47 is given by the late author a descrip- 

 tion of the fossiliferous layers of Hallbjarnastada, and at p. 49 a list 

 of species named by the present author.^ The specimens are partly 

 in the Museum of Copenhagen, partly in Stockholm. At p. 48 the 

 layer of Fossvogur, between Eeykiavik and Hafnarfjord, is more 

 speciallj'^ described. It contains — Saxicava rugosa, L. ; Mya trun- 

 cata, L. ; Tellina sabulosa, Spgl. {T. calcarea, Ch.) ; Nucula tenuis, 

 Mtg. ; Balanus, sp. These species indicate a more recent period
