The British Museum collection includes an example, in 
counterpart [C5253], from the Upper Lias of Alderton, 
Gloucestershire. It was rather larger than the specimen 
first described, being about 80 mm. long ; it is indistinctly 
defined at the posterior end, and incomplete anteriorly, being 
here about 12 mm. wide. Only scraps of the surface of the 
pen are preserved. There is an obscure ridge near each margin 
of the anterior part of the pen. The pen is almost perfectly 
flat, the median keel apparent throughout its entire length, 
the pen is split at the posterior end, nearly but not quite in 
the median line, as in the majority of examples. This shows, 
though very obscurely, the pseudo wing-like portion of the 
posterior part. 
The same collection contains a much larger example from 
the Upper Lias of Dumbleton, Gloucestershire. The specimen 
is merely the impression of the dorsal surface of a pen to which 
are attached a few fragments of the pen. It is 108 mm. long. 
Shows the broadly-rounded posterior end, which in this case 
is split open for a distance of about 20 mm. The greatest 
width of the pen is now about 46 mm., but each margin is 
very imperfect, so that originally it must have been much 
wider than this. The width at the anterior end must have 
been about 30 mm., for the impression of the half of the pen, 
which is all that is preserved here, is 15 mm. at the posterior 
part of the specimen, this impression of the dorsal surface 
exhibits obscurely the sudden binding of the lines of growth. 
All these specimens appear to be referable to the same species, 
viz. Teuthopsis. 
Brunelii Deslongchamps, originally described from the 
Upper Lias of Normandy. 1 The British Museum includes 
a number of examples from Normandy, chiefly from Curcy ; 
one, however, the original of Deslongchamps’ fig. 3, is from 
Amaye-sur-Orne [74009] and another from the Carrieres de 
Laquaine. The last-mentioned specimen is interesting because 
it is associated with the remains of an ink-bag and a portion 
of the mantle of the creature. The largest specimen [7401 1] 
is 170 mm. long, and lacks a small piece at the anterior end,
