INFUSORIA, RHIZOPODA. 
pi. iv., in alimentary canal of Discoglossus pictus, Naples. Development 
described. 
IJaptophrya gigantea, Maupas, C. R. Ixxxviii. p. 921. Intestine of 
Bufo pantheriniis^ Discoglossus pictus, and Rana esculenta. Body tra- 
versed by a contractile canal. Transverse fission takes place, with tem- 
porary union between the segments. 
SUCTORIA. 
Acinetopsis, Robin, (3) p. 537, based on A. rara, sp. n., id. 1. c. pi. xl. 
fig. 8. Distinguished from Acineta by absence of suckers and presence of 
a long and very mobile tentacle on the upper side of the body. Of. 
Ophryodendrum. On Sertularia, at Concarneau. 
Podophrya crustaceorum, Haller, Z. wiss. Zool. xxxiii. p. 395, pi. xxiii. 
fig. 40, on Crustacea of Italian seas. 
Anatomy and Physiology. 
Conditions of life and method of investigating cscvq- I nfusoria given by 
G. Joseph, Zool. Anz. ii. p. 114. 
Nucleoli discovered in Stentor cceruleus, Condylostoma patens, Spiro- 
stomum amhiguuni, E. Maupas, C. R. Ixxxix. p. 251, note, in numbers 
proportionate to that of the divisions of the nucleus. They occur also in 
most Vorticellina examined. Multiplicity of nuclei observed in Enchely- 
odon, Enchelys, Uroleptus, Oxytricha ; 1. c. p. 252. 
E. Serrano Fatigati, in a note on the influences of the different 
colours on the development and respiration of the Infusoria, C. R. Ixxxix. 
p. 969, states that violet light quickens, and green retards, the development 
of internal organs ; violet light causes small masses of them to become 
scattered quicker than other lights ; carbonic acid is produced most 
abundantly under violet, least so under green, light. Respiration is 
more active in violet, but less in green, than in white light.
