FROM NEW YORK, NEW JERSEY, ANt) GEORGIA. 147 



Distrihution. Lakehurst, N.J. ; Long Island, N.Y. ; Scotland (Orkney 

 Islands) (46) ; Ireland -(Mayo) (45). 



Those found at Lakehurst measured from 70—90 /jb in length and are 

 broader than the British variety ; those found at Good Ground, Long Island, 

 were 60-70 /x in length and smaller than the British. 



Var. ACicuLARis, var. nov.* (PI. 12. figs. 32 & 33.) 



Test larger than in the type, the fundus rather more acute and furnished 

 with either one or two erect spines, which may be flexuous ; the spines when 

 solitary often coinciding with the longitudinal axis of the test ; plasma and 

 pseudopodia normal. 



Length 84-94 yu. ; diameter 23-24 yu, ; aperture 12-14//,; spines 23-42//, 

 in lenuth. 



Habitat . Submerged sphagnum. 



Distribution. Clare Island, Mayo ; Inishbofin, Galway : Ireland (45) *. 



The spines of E. mucronata, Leidy, originate in scales at the extreme apex 

 of the test, which is prolonged into a sharp cone, whilst in the variety under 

 consideration the scales furnishing the spines are below the apical scales and 

 the flexure necessary in order to bring a spine coincident with the axis of the 

 test is a little distance above its base, 



EUGLYPHA CRENULATA, Sp. UOV. (PI. 12. figS. 34-37.) 



K alveolata par?, Leidy, pi. 35. figs. 2, 3, i, 15-18 (30). 



Test large, not compressed, either elongate-oviform or with sides tapering 

 from the hemispherical fundus in nearly straight lines to the aperture. 

 Fundus furnished with 2-6 stout scale-spines arising at nearly equal distances 

 from the apex. Aperture circular and bordered by two rows of finely denti- 

 culated scales, 12-14 in each row. The body-scales scutiform, with crenulated 

 lower margins. Nucleus large, placed posteriorly ; pseudopodia normal. 



Length 115-140 /t ; diameter 67-77/1. Aperture 25-30 /t. Length of 

 spines 20-50 /i. Body-scales 10-12 /t long. Nucleus about 35 (x in 

 diameter. 



Habitat. Submerged sphagnum, lakes, ponds, &c. 



Distribution. New Jersey ! (Leidi/) ; Nev/ York State, Long Island ; 

 Pennsylvania (Leidy). 



Distinguishing features. Is distinguished from U. scntigera and E. armata 

 by its crenulated scutiform body-scales and its greater size ; from E. aspera 

 by its smooth test and usually smaller size. 



Remarhs. This species appears to be represented by Leidy, pi. 35. figs. 2, 

 3, 6, 15-18, but the lower margins of the scales are not shown even in fig. 18 ; 

 the form represented by his fig. 3 is perhaps the most connnon, at any rate in 



* The Eoy. Irish Acad. Keport Xo. 65 of the Clare Island Survey was in the press when 

 this variety was found and its description could not be included in that paper {op. cit. pp. 40 

 and 62, notes).
