Clapabede (1. c.) acknowledges that Stein is fully justified in separating 
the Trichodines from the family Vorticellinciy hut is not quite sure that tho 
family Urceolarina of Stein is a natural one j for while the aflinity is acknow- 
ledged between the genera Trichodimiy Ehrb., and Urceolariay St., that of 
Trichodinopsis is not so apparent j and since the remarkable memoir of II. J. 
Clark, the affinities between the VorticdUna and Urceolarina would appear 
more considerable than that between the Trichodines and Trichodinopsis) 
indeed the resemblance may be said to be mimetic. The discovery of two 
ciliated Infusoria, differing both from Trichodina and Trichodinopsis is a very 
interesting fiict. One of these species had been discovered and described by 
Cohn as Trichodina auerbachii j it was found on a Dorisy and has since been 
found by Claparede on Thysanozoon tubercidatum (Delle Chiaje) j a second 
species was found on the branchim of Psygmobranchus protensusy Phil. : both 
species are placed in a now genus, Licnophoray and tho second species is 
called X. cohnii, Tho peristome of tho species of this genus recalls to mind 
certain species of Stylonychiuy a genus belonging to tho OxytrichinidcBy among 
the Hypotrich Infusoria, whereas their resemblance, on a first glance, to 
tho Trichodines is very remarkable. 
Tatem (1. c.) describes as new species the following ; — Stephanops longi^ 
sjnnatus, p. 252, pi. 10. fig. 2, and a marked variety of Cothurnia marilimay 
var. incisay met with at St. Leonard’s, pi. 10. fig. 3.

Spontaneous Generation. 
M. Donne, in a note entitled Experience relative aux generations spon- 
tam^es des animalcules infusoires,” states that ho took a newly laid hen’s 
egg, and made a minute opening in it towards tho summit, piercing tho yelk 
by means of a stylet previously heated to a red heat, thus allowing ji portion of 
the contents to escape j he filled up the egg witli some boiling water (dis- 
tilled) and hermetically sealed tho opening. The egg was left for five days 
in a room at the temperature of from 17 to 24 degrees j on being then opened 
and the contents exjimined with the microscope they were found to swarm 
with Yibriones. Compt. Rend. Ixiv. No. 1, 1867, p. 47 ; also Compt. Rend.
