'Grayella cyathophoraf gen. et spec, nov., Carter, 1. c. p. 190, pi. 7. No di- 
stinct generic diagnosis is given j but the description of the species is very 
minute j and the figures are characteristic. Is not this species but one of the 
many forms assumed by Papillina suherea, Sdt, ? 
Latrunculia cratera, g. et sp. nov., Bocage, 1. c. p. 161, pi. 11. fig. 2, St. lago. 
This sponge was found in some quantities of different shades of brown, im- 
planted on the stems of Goryonia at the bifurcation of their branches. The 
surface is mammillated, on each of the elevations there is an osculum ; the 
outer sarcode-layer is furnished with very remarkable spicules, compared to 
chessmen j the internal spicules are acerate.

Euglena tuba^ sp. n.. Carter, 1. c. p. 249, pi. 17. fig. 13, freshwater, Island 
of Bombay. The anterior portion of the cyst is extended into a tubular pro- 
longation, which ends ii\an open trumpet-shaped expansion. 
Uvella hodo, Ehr. Carter, 1. c. p. 250, gives an interesting account of this 
form, which he appears inclined to believe to be very nearly allied to Euylcna 
viridis, 
Volvox. Carter, 1. c, p. 257, makes some very important remarks on the 
forms appertaining to this genus. He considers V. aureus (fig. 2, tab. 4, Elir. 
Infus.) to be V. ylobator after impregnation of the spore-cells ; fig. 11, tab. 8, 
Uroglena volvox, to represent the small or spermatic cell, which, having 
passed into spermatozoa, has become liberated from the parent, but still 
swims about entire in an abortive form. Fig. 8, tab. 3, Sphcerosira volvox, is 
the male cell of V. globator, with most of the spores passing into spermatozoa. 
Fig. 7, tab. 3, Syncrypta volvox, is probably the spermatic cell of Volvox 
in different degrees of division. Fig. 9, tab. 3, Synura uvella, appears to 
be another form of the divided spermatic cell of V, ylobator, in which the 
spermatozoa are fully formed and have more or less left the cell, to which 
their tails still adhere. 
Eudorina elegans. Carter, h c, p. 254, regards Gonium pectorale, G. punc- 
tatum, and G. tranquilhim as but cell-group forms of this species. He also 
thinks Pandorina morum and P. hyalina to be large parasiticized cells of the 
same, and Perty’s Synaphia dujardinii to bo but an abnormal form, where 
several of the cells here and there take on the spermatoid development, while 
the rest become abortive. 
Glenoclosterium varians, g. et sp. n.. Carter, 1. c. p. 258, pi. 17. fig. 16. 
Cell-wall fusiform, spindle-shaped, elongated, acuminated, transparent. 
Body more or less inflated, and more or less confined to the centre, filled with 
protoplasm, granules, and chlorophyll, presenting a nuclear cell iu the 
centre, a red eye-spot at one end, and four or more large chlorophyll- and 
starch-bearing utricles arranged longitudinally, decreasing in size from the 
centre towards each extremity. Extremities attenuated, pointed, colourless, 
transparent. Size l-267th of an inch long, by l-1800th broad in the centre.
