14 SUPPLEMENT TO THE CRAG MOLLUSCA. 
but I believe it to be referable to the Russian fossil. Mr. Miller, of Ipswich, has obtained 
from the same locality a second specimen, and Mr. Harmer has very recently sent me 
another. It somewhat resembles a dwarf variety of JV. reticulata, but it is, I believe, a 
full-grown shell and specifically distinct, as described by Mr. Bell. The accidental 
coincidence in the adoption of the name is curious. Mr. Bell also gives it (loc. cit.) from 
the Red Crag of Waldringfield. 
Nassa pustiiina, 8S. Wood. Supplement, Tab. II, fig. 7. 
Spec. Char. NV. Testa parva, elongato-conoided, longitudinaliter costata ; costis 5—6, 
spiraliter striata ; striis paucis, magnis, elevatis ; anfractibus planiusculis apertura ovate ; 
labro extus varicoso, intus dentato. 
Awis, ths of an inch. 
Localities. Fluvio-marme Crag, Bramerton. Red Crag, Butley. Middle Glacial, 
Billockby. 
In Dr. S. P. Woodward’s list of Norwich Crag fossils this is inserted as “ Wassa ; 
sp. (slender pointed), Norwich ; examples in all collections ;” from which remark, I presume, 
it is not rare near Norwich. The varices are rounded, with a considerable space between 
each ; the suture is well defined, and the ribs slightly oblique, but the artist has made 
them rather too much inclined. It is very unlike all the other Crag Wassds, coming nearest 
to WV. consociata, but quite distinct ; it is identical in all respects with a shell m the Museum 
of the Geological Society presented by the late Jas. Smith, of Jordan Hill, but which is 
without aname, marked “ Raised Beach, Gibraltar.” It may, therefore, probably some day 
be found living in the Mediterranean area. It is by no means rare at Billockby. 
It is the shell referred to as VV. pusio in the paper by S. V. Wood, jun., and F. W. 
Harmer, in‘ Brit. Assoc. Reports’ for 1870, but I find the name puszo has been previously 
occupied.

Locality. Post-glacial, Kelsey Hill and Hunstanton. 
This shell is very common at Kelsey Hill, but I do not know it from any Glacial 
or Pre-glacial formation in Britam. The specimen figured was found by my son at Kelsey. 
Tt has a great range in the recent state. The shell figured under this name from Bordeaux 
is, I believe, distinct. A fragment of WV. reteculata, obtained from the beds of the Severn 
Valley, was sent me for inspection by Mr, G. Maw.
