tually agree, as well as with others, in my opinion, in having 

 two distinct sarcode regions, an inner more dense and an 

 outer more fluid ; but all the acknowledged species of the 

 latter — A. turfacea (Carter), A. viridis (Grenadier, if distinct 

 from the former), Greef's form (fig. 18) loc. cit., A. splnifera 

 (Greef ), A. Per ty ana (niihi) — have radial spicula with dis- 

 coid bases mutually approximated around the periphery of a 

 single globular sarcode body, whilst in Raphidiophrys viridis 

 (mihij, the spicules are crowded without order, and are not 

 discoid at one extremity. 



Genus, Pompholyxophrys (Arch.). 

 Synonym, Hyalolampe, Greef.' 



Generic characters. — Rhizopod composed of two distinct 

 sarcode regions — the inner a dense, coloured, globular sarcode 

 mass — the outer colourless, bearing a number of separate hya- 

 line globular structures, these disposed in a more or less thick 

 layer around the inner globe, which latter gives off more or 

 less elongate slender non-coalescing pseudopodia. 



Pompholyxophrys punicea (Arch.). 

 PI. XVI, fig. 4. 



Syn. Hyalolampe fenestrata, Greef.^ 



Specific characters. — Inner mass loaded with numerous scat- 

 tered, reddish or garnet-coloured augment granules, accompanied 

 by others, colourless or sometimes green ; outer region of great 

 tenuity, colourless, the spherical vesicle-like bodies, colourless, 

 hyaline, numerous, somewhat varying in size, arranged therein 

 so as to form a more or less thick stratum two or three deep all 

 over the periphery of the inner globe, leaving a hyaline mhiute 

 interval all round the latter, which gives off not very numerous 

 nor very long but very delicate pellucid linear pseudopodia, 

 some of which sometimes appear thicker above than below, that 

 is as if suddenly attenuated near the base ; no evident nucleus 

 nor pulsating vacuoles. 



Measurement. — Diameter variable ; that of inner body 

 averaging about y-^^o^th ; total, including outer region, averag- 

 ing: about ^4rTvth of an inch.
