B. Etheridge — Notes on Fossils from Red Romalonotus Beds. 155 



Sangidnolites distorted through pressure at the urabones, hut the 

 jjosterior side seems to show the ridge which characterizes Gijpri- 

 cardia ; the sharply defined concentric ridges, or lines of growth, 

 and the depressed umbones, are sufficiently clear to enable me, with 

 other characters, to refer it to the latter genus. The smooth deep 

 concave depressions between the sharp elevated lines of growth are 

 highly characteristic of Gypricardia and Ci/pricardites. I therefore 

 ]"efer Figs. 4 and 5, Plate IV. to Cypricardia. 



I know no British or foreign Devonian species to which I can. 

 refer it. A convenient name would be Cypricardia loevisidcus. This 

 cast somewhat resembles Orthonota (Cypricardia) semisulcata, Sow. 

 (Phillips, Pal. Foss. Dev. and Cornw. tab. 17, fig. 57), but is 

 a much larger shell, and probably the concentric ridges are sharper. 

 There is no appearance of the transverse furrows on the posterior 

 side, nor of the intermediate shorter ones mentioned by Phillips. 

 The fossil may, however, be referred to Cypricardia without doubt. 



Loc. and Formation. — Lr. Devonian, Smuggler's Cove, Torquay. 



2. Modiolopsis sp. (PI. IV. Fig. 6.) 



It is probable that Fig. 6 is only a portion of a much more 

 elongated shell resembling posteriorly an Anodonta or Sangidnolaria. 

 I was at first inclined to the opinion that this specimen might prove 

 to be allied to Myalina, which occurs in the Middle Devonian of 

 Exmoor, but I cannot detect the carina or ridge which characterizes 

 some of the Mytili and Dreissence. The nearest approach to this 

 fossil will be found in the genus Modiolopsis. 



The shell was evidently thin, elongated, and inequilateral, and the 

 hinge-area more or less straight (the ventral margin is not seen) ; 

 the posterior end was wider, probably, and higher than the anterior, 

 or much expanded. 



No trace exists on the fossil of ornamentation or sculpture save 

 broad undulating fold-like lines of growth. A smaller specimen, 

 not figured, belonging to the same species, shows the straight hinge- 

 line as seen in Modiolopsis and Modiola. The folds on the sides of 

 the shell are too coai-se and undulating for Edmondia, nevertheless 

 there is much in common with that genus in the smaller unfigured 

 specimen. 



As no sufficiently well-marked specific characters can be detected 

 by which to distinguish this fossil, it would be unwise to append 

 any specific name.

 3. Spirifera cultrijugata ? Eom. (PI. IV. Fig. 9.) 



This fossil, which is only an internal cast, is in so unsatisfactory 

 a state as to forbid accurate determination. It must either be 

 referred to Spirifera cultrijugata or S. disjuncta. Careful specific
