Good internal casts showing all the characteristic features of this 
species occur in the Kilmorie Beds, some of which show the muscle- 
scars extremely well. One specimen has a length of 32 mm. and a 
width of 44mm. Upfield Green+ has recorded this species from 
the Gedinnian of Cornwall. The species is restricted to the Lower 
Devonian.2 The species A. avirostris Krantz,? is scarcely separable 
from it, and the same may be said of A. rauffi Assmann.* 
Horizon.—Meadfoot Beds. 
Locality.—Kilmorie (8. 33, 44, 50). 
Note.—Since the publication of Part I of these Notes on the 
Fauna of the Lower Devonian Beds of Torquay (Grou. Mae., 
Vol. LVII, 1920, pp. 299-306, 341-7, Pl. IV) my attention has 
been drawn to the fact that after an examination of the types 
Rudolf Richter (Jahrb. k. preuss. geol. Landesanst., Bd. xxxvu, 
1, Heft 2, 1916, pp. 250-2, t. xxv, xxvi) has been led to consider 
that the original Crypheus lacuniatus F. Roemer is a synonym for 
Cr. rotundifrons Emmrich, and that Kayser’s Cr. Lethe is divisible 
into two distinct species, Cr. Lethee sens. str. and a new one Cr.
