SOME NEW DEVONIC FOSSILS 229 



Cypricardinia magna nov. 

 or cf. crenistriata Sandberger 



See Sandberger. Verstein. d. rhein. Schichtensystems. 1850-56. p. 263, 



pi. 28, fig. 5 

 Beushausen. Lamellibr. d. rhein. Devon. 1895. p. 178, pi. 16, fig. 9-13 



Shell large for this genus, somewhat variable in outline but 

 usually obliquely rhomboidal with very strong umbonal ridge, an- 

 terior beaks, very decided postumbonal slope which is deeply in- 

 curved, narrow anterior extremity widening backward. Hinge 

 somewhat curved, shell extended behind, lower margin slightly 

 incurved and sinuate. Length and greatest hight as six to five, 

 actual length 30 mm, high 25 mm. Some specimens are quite 



Cypricardinia magna or cf. crenistriata 



erect with the hight and length equal. Surface bearing strong 

 concentric lamellose and quite regular sculpture, on which the finer 

 ornamental lines occurring in many other species have not been 

 retained. 



This shell in its size and proportions is very closely like C. 

 crenistriata as figured by Beushausen from the lower and 

 upper Coblentzian of the Rhine. Species in the Grande Greve 

 limestone (C. distinct a Billings) attain its size and C. plan- 

 ulata Hall (Schoharie grit) has a similar contour but no other 

 form than that above cited is known to us which approaches it 

 both in size and contour. 



Lower Devonic. Moosehead lake. Baker Brook point, Me. 



Cardiomorpha (Goniophora ?) simplex nov. 



Shells elongate with anterior beaks ; narrow in front, widening 

 behind and with a very high and bluntly angular umbonal ridge 

 behind which is an abrupt posterior slope and in front a well marked 

 sinuosity or radial depression. The posterior extremity of the 

 shell is quite narrow and subacute.
