Gleichenia, 



Fig. 285. Fertile pinnules with sori. Magn. 5 diams. 

 Fig. 286. Sorus composed of four crucially arranged 

 capsules. Magn. 40 diams. 



II , Platyzoma. Sporanges collected in 

 point-like sori. Indusium spurious, formed 

 by the revolute margin of the leaf. Leaves 

 undivided. 



GLENODINIUM, Ehr.— A genus of In- 

 fusoria, of the family Peridinaja. 



Char. Carapace membranous, rounded or 

 oblong, with one or more distinct fuiTOws 

 furnished with vibratile cilia ; an elongated 

 or horse-shoe-shaped red (eye-) spot pre- 

 sent ; no horn-like processes. 



These organisms are doubtful Infusoria. 

 They are common in })Ools and bog-water. 



G. cinctum (PI. 24. fig. 10, a, h). Ovate or 

 subglobose, ends obtuse, yellow; carapace 

 smooth; eye-spot large, transverse and semi- 

 lunar; length 1-5/6". 



G. apiculatum (PI. 24. fig. 10 c). Oval, 

 ends obtuse, greenish - yellow ; carapace 

 smooth; eye-spot oblong; length 1-480". 



G. tahulatum. Oval, greenish-yellow; ca- 

 rapace granular, reticulated with prominent 

 lines ; ends acute or denticulate ; eye-spot 

 oblong; length 1-480".

GLENOMORUM, Ehr.— The Glenomo- 

 rum tingens of Ehrenberg (PI. 24. fig. 14), 

 which consists of aggregated revolving groups 

 of green bodies, with two anterior cilia, and 

 a red (eye-)spot, has been shown by Weise 

 and Stein to form the young state of Chlo- 

 ROGONIUM, which itself appears probably to 

 be a stage of development of Protococcus. 



GLE'NOPIIORA,Ehr.— Agenus of Ro- 

 tatoria, of the family Ichthydina. 



Char. Free; eyes two, frontal; rotatory 

 organ circular and frontal; tail truncated, 

 without toes. 



G. trochus (PI. 34, fig. 36). Body ovato- 

 conical, colourless, the turgid front and the 

 narrowed foot truncated; eyes blackish; 

 length 1-576"; aquatic.

GLOBULINA, Turp. = Glcegcapsa. 



GLOBULINE. — An animal substance 

 nearly allied to albumen, existing within 

 the coloured corpuscles of the blood and the 

 crystalline lens. It is amorphous.

GLCEOCAPSA, Kiitz.— A genus of Pal- 

 mellacese (Confervoid Algae), instituted by 

 Kiitzing to receive certain forms, distributed 

 among Hamatococcus, Microcystis, Soro- 

 spora, &c. by various authors. As we have 

 adopted it, it is distinguished from Palmella 

 by the persistence of the coats of the parent- 

 cells as envelopes enclosing their progeny of 

 several generations, to the number of 4, 16, 

 Q4, or more generations, the membranes 

 becoming confluent subsequently, however, 

 by solution, into a gelatinous mass. From 

 Coccochloris the chief distinction seems to 

 be in the persistence of the lamellae of the 

 parent-cells in the membranous condition, 

 and the globular instead of cylindrical or 

 elliptical form of the cells ; while the habit 

 is to form rather flat, irregular strata than 

 globose or papillose masses. From Proto- 

 coccus it is distinguished by the persistent 

 gelatinous investment. 



We give such of Kiitzing's species as are 

 British, with the synonyms as stated by 

 him; but they require further investiga- 

 tion.
