THE VOYAGE OF H.M.S CHALLENGER. 
As a fossil it lias been found by the above-mentioned authors, in the Middle Tertiary 
formations of the neighbourhood of Bordeaux. 
Lagena wrightiana, H. B. Brady (PL LXI. figs. 6, 7). 
Lagena wrightiana, Brady, 1881, Quart. Journ. Micr. Sci. , vol. xxi., N. S., p. 62. 
Test oval, flattened ; margin thin, furnished with a narrow peripheral border ; 
surface-ornament consisting of a number of longitudinal, parallel, excavated grooves, 
covering the two faces of the test except the central portions, which are smooth. 
Aperture encircled by a stout, sessile, phialine lip, entosolenian. Length, Ajth inch 
(0’28 mm.). 
This pretty variety, named after Mr. Joseph Wright, F.G.S., of Belfast, to whose 
courtesy I am indebted for many notes especially on matters connected with the present 
genus, was found in anchor mud from Nares Harbour, Admiralty Islands, 37 fathoms, and 
has not hitherto been observed elsewhere. 
Lagena schulzeana, H. B. Brady (PL LXI. fig. 10). 
Lagena schulzeana, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi., N. S., p. 62. 
Test oval, compressed, subcarinate ; faces flattened ; neck wide and very short, 
finished with a rounded lip. Surface-ornament consisting of a number of more or less 
regular transverse bars, horizontal in the middle and bent downwards at an angle, near 
the periphery. Length, ^Lth inch (Off mm.). 
There are several varieties of Lagena in which the surface decoration consists of raised 
longitudinal lines connected by a system of transverse bands ; but Lagena schulzeana 
is, so far as I am aware, the only form in which the transverse ornament appears by itself. 
The habitat of the species is — off Paine Island, Torres Strait, 155 fathoms.

In Lagena trigono-marginata the three salient angles of the test are emphasized by 
a marginal beading with acute or subcarinate edge. The normal form is ovate or pyri-
