Lagena alveolata Brady var. nov. separans (PI. 21, fig. 5). 



Test compressed, almost circular in outline, ovate, or pyriform. 

 Four independent, narrow loops at, the base, two on either side. 

 Entosolenian tube short and coiled. Orifice rather compressed. 



I think this interesting form should be treated as a variant of 

 L. alveolata, rather than as one of L.,aitricidata, the two loops on 

 either side of the base being separated. ,The type form is " fur- 

 nished with a median and two lateral carinae, which unite to 

 form two loops on either side of the test." There are over forty 

 on the slide. Localitfj : Chiefly Nos. 3, 13, 17, 18, 28, 30, 32. 



Lagena clypeato-marginata Rymer Jones var. (PI. 21, 



fig. 6). 



Lagpjia vulgaris Williamson var. clypeato-marginata Rymer Jones, 

 1872, p. 58, pi. 19, fig. 37. 



Although not quite typical, I think the specimens may come 

 under this heading. There are no spines and the base of the 

 chief keel is not always serrated. Some of the specimens have 

 the space between the orifice and the body of the test shorter, 

 and the keel at the base more rounded off, than in the one 

 figured. Eight found. Locality : Nos. 8, 14, and several other 

 stations. 



Lagena clypeato-marginata Rymer Jones var. nov. 

 crassa (PI. 21, fig. 7). 



Of this very robust variety there are only two specimens, and 

 they are in good condition. The neck is decorated with four 

 stout costae, two on either side. The lower part of the body of 

 the test is pitted, in most cases irregularly, but sometimes the 

 markings are arranged in lines. The lower edge of the pitted 

 portion projects as a flange. Locality : Nos. 3, 14. 



Lagena magnifica sp. nov. (PI. 21, fig. 8). 



Test compressed, occasionally round in section. The neck is 

 long and the orifice phialine. The base is apiculate and there are 

 two spines, one on either side of the apiculate process. The body 

 of the test is covered at regular intervals with short, blunt,
