size, rare. One species, resembling a Nonionina, is 

 rather common: it is middle size, and has all the septa, 

 foramen, &c, very much obliterated. Another most 

 beautiful form is very common : it is small, semi- 

 transparent, and veiy distinct ; the segments overlap 

 one another, and in the 3 or 4 segments the septa 

 form a fork-like arrangement ; the foramina are 

 clearly seen with a low magnifying power. This 

 one, with figs. 33 and 34, I cannot name, and I should 

 feel obliged if anybody could help me to name it.

Of the genus Textularia, small, transparent, and 

 perfect specimens were very common, but the larger 

 end opaque ones rare. Five species of Textularia 

 were found, but there is only one of them that I can 

 name, and that is Textularia abbreviata, D'Orb. : it 

 is small, transparent, and rare. Two other species

were small and transparent. One of these I have 

 figured to show the points protruding from the side 

 of the shell. One of the opaque forms is about the 

 5 * T of an inch in length. The chambers go down 

 to a fine point, are rather wide at the top, and a slight 

 bit wider in the middle. It is very difficult to recog- 

 nize the species on account of the middle portion 

 being covered over by some arenaceous matter, there- 

 by hiding the characters that in some respects 

 determines the species. 



Of the Lagenida, some very good species here 

 represented this family. The first of these is the 

 neckless variety of Lagena sulcata, Walker and Jacob. 

 It is a small form, and rather rare : only one of the 

 three specimens obtained show the lines that traverse 

 the shell distinctly. Lagena globosa, Montagu (see 

 fig. 26). This form is very small and rare. It is a 

 globular shell without any strire or foramina visible. 

 Lagena disto?na politia, Parker and Jones. This 

 is an elongated species, having the neck about half 

 the size of the body. All three of these species of 

 Lagena have been figured by Messrs. Parker and 

 Jones in their paper on the Arctic Foraminifera, in the 

 Philosophical Transactions for 1865, Part I. Cris- 

 tellaria rotulata (fig. 36), Lamarck ; small and middle

size, rather rare. A good specimen, showing the 

 septa well. Another peculiar species is an elongated 

 form traversed by rather deep furrows, as in 

 Lagena sulcata, with the septa placed in rather 

 irregular positions. Four good examples were ob- 

 tained, all showing different characters (see fig. 34). 

 The Miliolida family was here represented by three 

 very characteristic species. The first was Triloculina
