2. Euglypha compressa, Carter. ? Difflugia ciliata, Ehrenberg. 



Test flatteiied-ovoid ; lateral border obtuse, and furnished with 

 spines towards the fundus. Surface of test covered with scales as 

 in the former species. Oral scales angular and denticulated. The 

 largest specimens measured 0.1 mm. long, 0.06 mm. broad, and 

 0.03 wide or thick ; with the mouth 0.052 broad, and 0.026 wide. 

 Smaller ones measured 0.08 mm. long, 0.036 broad, and 0.024 wide. 



Abundant at Absecom, N. J. 



From the same locality I obtained larger specimens of the same 

 form, but without spines, and also larger specimens covered with 

 spines over three-fourths of the l)road surfaces, as well as on the 

 lateral borders. I propose, at a fitting opportunity, to investigate 

 these still further, before expressing an opinion in regard to their 

 identity with E. compresaa. 



3. Euglypha spinosa, Carter. 



Test compressed-oval ; lateral borders subacute, and furnished 

 with narrow delicate dagger-like spines ; mouth unusually broad, 

 and narrow. Surface of test covered with oval scales, as in the 

 former species, but the oral row does not project beyond the mar- 

 gin of the mouth. The specimens usually measure 0.112 mm. long, 

 0.072 mm. broad, and 0.036 wide; with the mouth 0.048 broad, 

 and 0.008 wide. 



This remarkable species is abundant at Absecom, and at Lake 

 Hattacawanna, N. J. 



4. Euglypha cristata, n. s. 



Test oblong, or cylindro-ovoid, covered with elliptical scales as 

 in the preceding species. With from four to six projecting angu- 

 lar, finely denticulated oral scales. With a tuft of six spines 

 radiant from the very summit of the test. The largest specimens 

 measure 0.05 mm. long by 0.018 broad, with the mouth 0.01 broad. 

 The smallest are 0.04 long by 0.012 broad, witii the mouth 0.008 

 broad. 



A small and apparently well-marked species, common at Abse- 

 com, X. J. 



5. Euglypha globosa, Carter 



Test globose or oval, with a short neck or rim to the mouth. 

 Surface covered with circular scales. The smallest species, approach- 

 ing in character the next genus. Length from 0.02S to 0.048, 

 breadth from 0.02 to 0.04 mm. 



Common at Absecom and Lake Hattacawanna, N. J. 



6. Euglypha brunnea, n. s. 



Test flattened-spheroidal, brown in colo?*, covered with imbri- 

 cate oval scales. Mouth transversely elliptical, with the edges 

 alwa^'s irregular or ragged. Length of largest specimens 0.1 mm., 

 breadth 0.088, and width 0.036, with the mouth 0.04 broad.
