SOME NEW DEVONIC FOSSILS 



159 



Dalmanites veiti nov. 



Associated with specimens of D. p h a c o p t y x from the lime- 

 stone hihs behind Peninsula, Gaspe Bay, are abundant pygidia and 

 cephala of uniform size, unlike the species with which they are as- 

 sociated as well as with any others of our acquaintance. These 

 pygidia are relatively small, subequally triangular, flattened above 

 and rather abruptly sloping at the margins ; apparently without tail 

 spine. There are 11-12 lateral ribs, 6 or 7 of which are grooved 

 medially. The axis bears 13-14 segments. The upper limb of 

 each of the divided lateral ribs carries 2, 3 or 4 pustules so devel- 



Dalmanites veiti. The underside of the cephalic doublure X2 and three pygidia 



natural size 



Oped as to overhang the sulcus, while each segment of the axis 

 bears a single row of 5, 6 or 7 pustules. The length of these 

 shields will average 23 mm with an anterior width of 29 mm. 



The cephala belonging to these pygidia are not completely pre- 

 served but indicate a type of simple glabellar lobation as in D. 

 m i c r u r u s, with closely pustulose surface. The border is smooth 

 laterally but in front is extended into a short crenulated snout or 

 shelf as in D. p 1 e u r o p t y x and D. d o 1 b e 1 i though less 

 expanded at the sides than in either of these. 



There is undeniable similarity between this fossil and the D. b i- 

 s i g n a t u s described by me from the Oriskany of Becraft moun- 

 tain.^ The latter, known only from the pygidium, has the part nar- 

 rower and more elongate and its axial pustules are so arranged as to 

 make a longitudinal median double row. That species we have noted 

 {op. cit.) is allied to D. d e n t a t u s Barrett from the same horizon 

 in Orange county, N. Y. but in ignorance of the cephalon of the
