PROTOZOA. 
Carpenteria utricularis and monticularis, Polytrema miniaceum^ Gypslna 
melohesioides^ &c., (4) Gulf of Manaar. 
Gypsina, Carter, (4) p. 444. 
Carpenteria, (G) p. 84. Recharacterized as having the pseudopodia 
thread-like and branching, and the test formed lirst of sponge spicules 
and similar foreign bodies, which are overlaid by a delicate chitinous 
cuticle and a calcareous layer, perforated by pore-canals ; it has one or 
more openings, and is attached by the aboral side. It constitutes a 
transition from the arenaceous to the calcareous forms. 
Polytrema miniaceum^ (6) p. 85, pi. vii. The great variation in size 
illustrated by tables of comparison. The canals and cavities have a 
chitinous lining ; the contained spicules are derived from sponges. 
Spirillina vivipara, Ehrb., (6) p. 88, pi. viii. figs. 1 & 2, Mauritius. 
Oolina striata and caudata, D’Orb., (6) p. 89, united as Lagena striata, 
pi. viii. fig. 3. 
Entosolenia lucida, (6) p. 89, pi. viii. fig. 4, marginata, quadrata, midis, 
aspera, 1. c. pp. 90 & 91, pi. viii. figs. 7-12. The two latter were first 
described as fossils by Reuss. 
Pavonina jiabelliformis, D’Orb., (6) p. 91, pi. viii. figs. 13-15. 
Te'jotilaria folium, (6) p. 92, pi. viii. figs. IG & 17, agglutinans, ibid. 
pi. ix. figs. 1-8. 
Bolioina punctata, ihehaica, qdicata, (G) pp. 94 & 95, pi. ix. figs. 9-13. 
Several species, including some under the names Textularia, Grammo- 
stomum, and Bolivina, are cited as synonyms of these. 
Discorbina concamerata, Mont., includes liosalina americana, D’Orb., and 
probably Rotalia veneta, M. Schulze, &c., (G) p. 9G, pi. ix. figs. ; D. globu- 
laris and D. mcequalis, D’Orb., 1. c. pp. 9G & 97, pi. ix. figs. 18 ik 19. 
Rosalina poeyi, D’Orb., (6) p. 97, pi. x. figs. !-§, Mauritius, = Cymbalo- 
^om,- which genus is a higher form than Discorbina by virtue of the 
lateral openings of the chambers. 
Rosalina bulloides, D’Orb., (G) p. 99, pi. x. figs. G-9, = Tretomphalus, g. n. 
Glohigerina bulloides, (G) p. 92, Mauritius. 
Haliphysema, (6) p. 74. Recharacterized :as a Rhizopod. Envelope 
consisting of a thin chitinous sheath, beset with sponge-spicules or other 
microscopic foreign bodies ; at the free end of the sheath the foreign 
bodies are aggregated into the form of a head or club, at the fixed end 
into a disk-like form. 
Haliphysema tumanowiczi. E. R. Lankester, Q. J. Micr. Sci. xix. p. 476, 
pl.xxii.,has minutely examined the soft parts of this form, in specimens pre- 
pared, sent to him b}" W. S. Kent from Jersey, and in consequence refers it 
very decidedly to the Arenaceous Foraminifera. Threads of protoplasm 
containing vesicular nuclei can be detected spreading over the spicules 
outside the test. The central mass consists of a continuous core of finely 
granular protoplasm, apparently vacuolated by spaces filled with a less 
dense substance ; it is devoid of cell-structure and cavities ; there is no 
distinct differentiation of a cortical substance ; the protoplasm contains 
large numbers of spherical thick- walled vesicular nuclei, comparable to the 
similar bodies found in Orbitolites, Labyrinthula and Chlamydomyxa. 
Anteriorly, the protoplasm is segmented into egg-like germs, which are
