662 RIIIZOPODS OF SVDXEY AND LISMORE, 



Orifice proportionate!}^ wider than in the type. Generally armed 

 with a circle of spines behind, 1 to 10 in number, generally 3 or 

 4. Scales as in type. 



Length 65-133, breadth 30-76, orif. 15-38, spines up to 60/x 

 long. 



Lismore (185, 308, 312, 327, 337); Botany (155). 



Apparently much rarer than the type, though common enough 

 locally at Lismore; even the Botany specimen is not exact. It 

 has the same range of dimensions as the type, but is of quite a 

 distinct shape. Body-scales 8x6, 10 x 8, 11x8, lU x lOhfi. 



EUGLYPHA ACANTHOPHORA (Ehr.) Pert}^ (PI. xl., f.4). 

 Length 49-70, breadth 30-45, orif. 12-19, spines up to 27/xlong. 

 Everywhere, common. (En. alveolata Duj.). 



Var. ELLIPTICA, n.var. (PI. xl., f.5). 



Test narrow, elliptic, almost cylindrical, rounded behind; sides 

 very slightly arched, in general direction parallel, slightly turned 

 in at the mouth. Generally without spines. 



Length 70-90, breadth 30-47, orif. 13-19/x. 



Guildford (45, 60); Auburn (146); Lismore (185, 308, 337). 



This form, not uncommon where the type is found, is exactly 

 like En. tuhercidata v. minor (Taranek) Wailes in Cash, I.e., iii., 

 PL 35, f.3, but more than twice the size. I do not see how En. 

 tuberculata is to be identified from Dujardin's figure and descrip- 

 tion, the shape of the body-scales not being given. The form 

 that I figure certainly belongs to Eu. acanthophora, as I have 

 noted it with the typical encystment figured by Penard (under 

 Ell. hrachiata), Faune Rhiz., p. 505. 



Var. GRACiLLiMA, n.var. (PI. xl., f.6). 



Test slender, almost exactly cylindrical, generally spineless 

 but noted with spines; dome hemispherical; sides fiat, running- 

 straight down to the mouth. 



Length 70-76, breadth 25-32, orif. 13-15, spines 26/x long. 



Auburn (68); Guildford (84); Lismore (338). 



A very beautiful but very rare form. There seems to be con- 

 siderable doubt about the characteristics of En. acantfwpJtorn
