It was particularly gratifying to meet with this form, the repre- 

 sentative of a genus for which I have been searching nearly twenty 

 j^ears, and hitherto known only by specimens obtained by Prof. 

 Seguenza from the ^Miocene rocks in the immediate vicinity of Mes- 

 sina. I may add that I have also had the good fortune to find the 

 typical form, as well as the elongated variety, in some of the soft 

 deposits collected by Dr. Guppy in the Solomon Islands. With 

 respect to the somewhat anomalous structure of the test, I have at 

 present nothing to add to what has already been written on the 

 subject.

Some misunderstanding has arisen in connexion with this species 

 from its insufficient illustration by the figures in the " Yienna- 

 Basin "' monograph. Through the ever-ready kindness of Herr 

 Xarrer, of Yienna, I have had the ox^portunity of examining a 

 number of the original d'Orbignyan specimens, and I find that the 

 tapering of the segments towards the distal end, which has been 

 regarded as a distinctive feature, is at most exceedingly slight and 

 often cannot be detected at all ; indeed some of the shells are quite 

 undistinguishable from the figures given by Dr. Schwager from Kar 

 Mcobar specimens. The species occurs in the soft deposits of the 

 Solomon Islands as well as in those of Fiji, and the same variability 

 vdthin certain limits may be noticed in all.

Only one or two examples, and those in the fistulose condition.

The elongate, elegant variety figured in the ' Challenger ' Eeport, 

 pi. Ixxiv. figs. 13, 14. 



57-60. Sagetnta, spp. 



Sagrinm are abundant in these deposits and show a tendency, 

 especially noticeable in S. virgula and S. raijlianus, to become com- 

 pletely ]S''odosariform. 



73. SpH^EOHtixA OEXATA, sp. uov. (PI. I. fig. 4.) 



Test spherical or subspherical, slightly excavated at the umbili- 

 cus ; consisting of an involute spire, of which about four chambers 

 are visible externally, the ultimate segment occupying nearly one
