EXPLANATION OF PLATES V., VL, VIL 



Plate V. 



F'kj. 1. Aranebous cell under spherical distension, about to become plani- 

 forni, from the brackish water in the marshes of the ishuid of 

 Bombay; l-400th of an inch in diameter: («) peUicula and dia- 

 phane ; (A) sarcode and granules ; Cc) space unoccu])ied by sar- 

 code ; ((/) nucleus in its capsule. 



Fifj. 2. Section of ditto through the nucleus, showing the same parts 

 marked with the same letters : (e) nucleus ; {d) central cavity now 

 distended by water. 



Fig. 3. Amceba quudrilineutn, H. J. C. (n. sp. ?), imder reptation : («) din- 

 phane ; (6) molecuhc of sarcode ; (c) vesicula; !/Z) nucleus and 

 capsule ; (e) digestive globule containing a fragment of OacU- 

 latoria. 



Fig. 4. Aynceba Roeselii{l), Duj. : (a) "granules ;" (6) vesicula; (£j nu- 

 cleus. 



Fig. 5. Amoeba Gleichenii (?), Duj. : (a) discoid ovules of different sizes, 

 the largest l-28()nth of an inch in diameter ; (b) one more mag- 

 nified showing the capsule ; (c) " granules ;" (d) portions of 

 food; (e) capsule of nucleus empty; (/) vesicula. Animal 

 about l-400th of an inch in diameter when spherical. 



Figs. G-8. Ditto, becoming capsuled. 6. First stage, all extraneous matter 

 thrown off, peduncle formed, but pellicula still admitting of (b) 

 expansions; («) ovules and granules. 7- Capsule too much 

 hardened to admit of expansions of the diaphane. 8. Capsule 

 formed, rough, yellow, about 1-oUOth of an inch in long diameter. 



Fig. 9. Eugleno (viridis, mihi), Ehr., encajisuled, capsule rough, of a vel- 

 lowish-brown colour : («) red-body next the peduncle. 



Figs. 10-16. Amfjeba radiosu (?), Duj., showing nucleus in different stages 

 of " granulation." 10. (a) nucleus enlarged, gramdar. 11. Nu- 

 cleus still more enlarged, (12) presenting first sulcus of dupli- 

 cative (?) subdivision. 13. Same process ending iu the production 

 of a mass of spherical, delicate, transparent, granuliferous cells. 



14. Parent nearly effete with only two of the s])herical cells re- 

 maining, the granules of which have become large, free, separated 

 from each other and endowed with rapid locomotive power. 



15. One of these cells more magnified. 16. Plane or actino- 

 phorous form of ditto previous to hardening of the pellicula and 

 develo])ment of the granules. 



Fig. 17- Ditto in conjunction. 



Fig. 18. Ditto, another pair, just after separation. ' 



Fig. 19. Actinophorous form df a species of Palmellea {"?), Kg, like 



GlcBocapsti grunosu. Kg . bat with cells, separate and sohtary. 

 Fig. 20. Nucleus of Anuvba under '* granulation," presenting the second 



sulcus of duplicative subdivision. 

 Figs. 21-23. Different forms of botnoidal granuliferous cell-development 



of the nucleus in Amabee. 

 Fig. 24. Amoeba RoeseliiC?}, Duj., presenting a nucleus undergoing botry- 



oidal development : (a) mammilliform projection of vesicula j)re- 



paratory to discharging its contents. 

 ■" Fig. 25. Euglypha alveolata, Duj. : («) sarcode, granules, and molecula^; 



(b) nucleus and capsule (the former verv seldom visible except in
