At page 560, the 15th article of this paper is headed " Paleeocrangon prohlematica Schloth. 

 Taf. XXII. Fig. 2." Schlotheim's specimen of his Trilohite^ proUeniatictis is, Schauroth 

 says on the authority of Bronn's Nomenclator, no more to be found. Schlotheim's collec- 

 tion went into the Berlin Museum, but there Beyrich informed him the specimen no longer 

 e.Kisted, and had been in vain searched for by Quenstedt. Schauroth considers that a little 

 fossU from the Zechsteindolomite of Pcissneck is the same species as that which 

 Schlotheim described and figured. It has the exterior "iiberall chagrinirt und uberdiess 

 mit verschiedenen Hockern geziert." "Das Kopfschild ist von der Seite gesehen fast 

 dreieckig und zeigt an der vorderen Seite knotige Erhohungen, welche als InsertionsteUen 

 der Fiihler, Fresswerkzeuge und selbst der Augen gedeutet werden diirf ten," " Das 

 BrustscJald ist das grosste von alien Segmenten." The back is carinate, and the general 

 appearance agrees very nearly with Kirkby's Prosoponisais problemaiicus, but Schauroth 

 seems to have regarded the pleon as the head. He thinks the nearest palaeozoic forms are 

 to be found in Gitocrangon and AdelophtJialmus. Identifying it, rashly as I think, 

 with Schlotheim's species, he says, " Ich schlage vor dieses Geschlecht Palteocrangon (aus 

 TToXatos und r; Kpayyuiv, ahnlich dem Eichter'schen Gitocrangon, gebildet) zu nennen, den 

 Korper selbst also Palxocrangon problematica Schloth. zu bezeichnen."

 mouth of the Bay of Fundy, New Brunswick. Smithsonian Contributions to know- 

 ledge. (Accepted for publication, January, 1858). Washington, 1854. 



The Island of Grand Manan "is more properly an archipelago than an island." " It is surrounded 

 on all sides by deep-water (a hundred fathoms or more)." Stimpson adopts Dana's 

 division of the Tetradecapoda into Isopoda, Anisopoda and Amphipoda. In the second 

 division he describes Tanais filtm, n. s. Among the Amphipoda he gives Caprella lobata, 

 Krbyer, which is Caprella linearis, Linn.; Caprella sanguinca, Gould, and Caprella 

 longimaniis, n. s., both of which in Mayer's opinion are too briefly described for recognition, 

 though the latter may be Caprella acanthifera, Leach. Caprella rohusta, n. s., which 

 Spence Bate renamed Caprella stirnpsoni, because the name Cajnella rolnista was preoccupied 

 by Dana, is restored to its original name by Mayer, on the ground that Dana's Cap>rella 

 rohusta falls to Caprella acutifrons, Latr. Caprella rohusta, however, must be considered 

 to have lapsed as a synonym, u^gina spinosissima, n. s., is by A. Boeck with a % and by 

 Mayer without one, made a synonym of Boeck's later name JEgina echinata. This identifi- 

 cafcion is disputed by G. 0. Sars, 1885. " Caprella spinosissima, Norman," from the
