rounded, clavicle slender, nearly erect, and reaching halfway to base. 

 Beak low, terminating slightly anterior to the middle. 



Dimensions.— M 1802, 18^ by 12 mm. (65 per cent), M 1803, 18 by 

 13 mm. (72 per cent). 



Formation and locality. — Pembroke formation, gray splintery shales 

 outcropping near Oak Hill, northwestern Pembroke (loc. No. 1.43.9 

 A). 



Type-specimen.— Cat. No. 62886, U.S.N.M. 



NUCULITES GALEUS, new species. 



Plate 11, fig3. 1, 14, 19c; plate 12, fig. 2. 



Shell elongate-oval, the posterior end narrow and subangular, the 

 anterior somewhat narrowed and evenly rounded. 



The beak terminates at about the anterior third. The body of the 

 shell is subcylindrical, swollen in the middle and tapers down toward 

 both ends. The umbonal ridge is near the cardinal margin, its outer 

 slope abrupt and rounded off toward its outer end. The umbonal 

 furrow is faintly expressed and its termination forms a slight sinus 

 at the margin. The clavicle is slender, reaches halfway across the 

 shell and slants obliquely forward from the beak. The concentric 

 growth-lines are distinct, the finer concentric lines also are in evi- 

 dence. 



Dimensions.— Trsinsverse length 29 mm., height at beak 12 mm, 

 (41 per cent). Tip of beak 11 mm. from front end; the lower end of 

 clavicle, 6^ mm. from front end. 



Formation and locality. — Pembroke formation, splintery gray shales 

 on south side of Pennamaquam River at Kelly Point and westward, 

 Pembroke Township (loc. No. 5.3.2 A). 



Remarks. — Several specimens (one figured) from this same locality 

 have the same general form. Specimens from the Oak Hill (loc. No. 

 1.43.9 A) outcrop of probably the same shales, have the same form. 

 Oie of them is given on plate 12, figure 2. Another specimen from 

 the Kelley Point shales (loc. No. 5.3.2 A) is figured (pi. 11, fig. 1) and is 

 referred to this species. Their affinities with both N. corrugatus and 

 N. speciosus are apparent.

NUCULITES PELOPS, new species. 



Plate 11, figs 3, 7, 19a. 



Shell erect, obliquely ovate, height greater than the transverse 

 diameter; beak narrow overarching the hinge. Shell moderately 

 convex; posterior surface gently sloping off to the hinge and pos- 

 terior margin; the anterior slope more abrupt than the posterior. 

 The posterior margin forms a blunt angle with the hinge margin and
