120 S. Y. WOOD ON MOLLTTSCA FROM THE UPPER 



seeing that N. conglohata has not yet been found in the Coralline 

 Crag, as have the other two shells mentioned ; bnt such, neverthe- 

 less, is my belief. 



Fusus Waelii, Nyst. 



Two perfect specimens of this Oligocene species, one of which 

 precisely agrees with fig. 2 a of plate vi. of Yon Konen's work on 

 the Middle Oligocene, were sent me by Mr. Reed, of York. They 

 had been obtained from the excavations for Coprolite in the Boyton 

 Marshes. As these excavations are, from their position, flooded with 

 water, I am informed by Mr. Charlesworth that it is difficult to say 

 what division of the Crag they arc in; for peculiarly Red-Crag 

 species are intermixed with Coralline Crag ones. Mr. Bell, how- 

 ever, tells me that in the excavations referred to, about 18 inches 

 of Coralline-Crag are overlain by some Red Crag, and that, in work- 

 ing, the labourers mix the two together, so that it is only from the 

 colour of the specimens and the character of the shell that an 

 opinion can be formed as to the division to which they really belong. 

 If, therefore, F. Waelii belongs to the Crag, it is probable that it is 

 to the Coralline, the colour and condition of the shells of which 

 formation it possesses. The worn specimen described in the Sup- 

 plement to the ' Crag Mollusca,' p. 29, as Fitsus crispus (Tab. xi. 

 fig. 10) is possibly only a specimen of Fusits Waelii. 



Mtjeex Reedii, S. Wood. 



A perfect specimen of a Murex, obtained by Mr. A. Bell from the 

 Coprolite excavation in the marshes at Boyton, has been sent me 

 by Mr. Reed. In size and general appearance it resembles the 

 figure of M. Haidingeri, Homes, given by Dr. Homes in tab. xxiii. 

 of his work on the Vienna beds, but differs in not having any trans- 

 verse or spiral stria?, and in possessing some denticulations on the 

 inside of the outer lip. I have assigned to it the above specific 

 name. If a Crag species, it doubtless belongs to the Coralline 

 Crag, the colour and condition of the shells of which formation it 

 possesses. 



Chemnitzia senjsteiata, S. Wood. 



A small species of this genus was obtained by me from the Coral- 

 line Crag of Sutton. It is a quarter of an inch in length, has 

 slightly convex volutions, and somewhat resembles the figure of 

 Scalaria quadristriata, Phil., as figured by Dr. Speyer, Conch. Cassel 

 Tert. t. xxiv. f. 9 ; but my shell has a vertical columella, and 

 belongs to the genus CJiemnitzia. 



Scalaeia torulosa, Brocchi (Conch, foss. subap. p. 377, tav. vii. 

 f. 4). 



A specimen of this species, obtained by Mr. A. Bell from the Red 

 Crag of Waidringficld, has been sent to me by Mr. Reed. It is 

 doubtless only derivative in the Red Crag ; but from what bed it was 

 derived I do not venture to suggest.
