Man (1863, p. 217), and most probably, the specimen on which this 

 rested was the one said by Mr. Gunn to be from the " Laminated 

 Beds " at Mundesley (Geol. Norfolk, 1864), and now preserved in 

 the Norwich Museum. This specimen is a fragment of a tusk about 

 five and a half inches long, and one and a half inch in diameter, 

 showing the very characteristic twisted condition so distinctive of 

 the tusk of this species. 



DelpMnics delphis ? — Mr. A. Savin, of Cromer, has in his Collection 

 four small Cetacean vertebras from the " Forest Bed " of Overstrand, 

 near Cromer. One of these is a middle caudal vertebra, which 

 agrees so precisely with a corresponding vertebra in the tail of a 

 common Dolphin that there can be little doubt as to its belonging 

 to that species ; but seeing that in other species these vertebree are 

 very similar, it seems best to place a note of interrogation after the 

 species. The terminal epiphyses of this vertebra are firmly anchy- 

 losed to the centrum, the greatest antero-posterior extent of which 

 is about 1-0 inch, its greatest width 1'4: inch, and its height without 

 neural spine 1*6 inch. 



DelpJiinus, large species. — The only other vertebra of the four, 

 above mentioned, which is in a condition for comparison, is likewise 

 from the caudal region, but from a more anterior position. Its 

 terminal epiphyses are wanting, never having been anchylosed. 

 The antero-posterior extent of the centrum is in its present condition 

 about 1-3 inch, its height and width being each about two inches. 

 In form this vertebra closely resembles the one referred to Delphinus 

 delphis, but its larger size corresponds better with the skeleton of 

 D. tursio preserved in the Royal Coll. Surg. Museum ; the agreement 

 in form, however, is not sufficiently close to justify one in referring 

 it to that species.

 Cambrian of Westrogothia, Oland, etc. — The Cambrian Rocks are 

 shown in several other localities in Scania. The basal sandstones 

 (Lugnas or Eophyton sandstones) near the Baltic coast, near 

 Delperod. The Hardeberga sandstones (Fucoid Sandstone) are 

 found wherever the Archaean is bared, as near Rostanga, Lund, 

 Eljarcid, and Cimbrishavn. Sections of the Alum schists are rarer. 

 The most perfect is that of Kiviks Esperod on the Baltic, where the
