intermediate gradation, and on this account Mr. Brady has, m 

 liiy work just published, made H. rectum a synonym of H. 

 afff/Jatinans. But I tliink the name may be very wall retained 

 as a varietal distinction. In the material now under review 

 they assume very distinct appearances without any intermediate 

 forms that I have observed. 



HoiyJoplirngmium Q) Canariense, d'Orb. — There are a few 

 small nautiloid examples of Haplopliragmium in most of the 

 samples from Hergot, but they are in all cases very badly pre- 

 served, having been subject to much comj)ression and conse- 

 quent distortion. In some instances the pressure has been 

 applied laterally, by which the two sides of the shell have been 

 crushed together, and in others the pressure has operated on 

 their peripheral margins, so as to reduce them to an oblong 

 shape. In consequence of such distortion the determination 

 of these minute species is a matter of some difficulty, and has 

 been impossible in the short time and meagre material at my 

 disposal. Some of the best preserved specimens show a resem- 

 blance to H. canariense, to which I have for the time being- 

 relegated them ; but it is probable that with better specimens 

 at command it will be found that there are more than one 

 species brought under this determination. Dr. Stache, of 

 Vienna, has figured two species of Haplopliragmium from the 

 Tertiaries of jSTew Zealand, and it is not unlikely that the 

 examples in Hergott material may possess sj)ecific relation- 

 ship to these. IL. canariense is of world-wide distribution, 

 although, unlike H. agglutinans, it is a characteristic shallow 

 water species. It has not been hitherto known as fossil in 

 rocks earlier than the Pleistocene. 



HapJopliragmium, sp. — Two examples of what appear to be 

 an undescribed form of this genus were found, one at a depth 

 of about 45 feet and the other at about 200 feet. They consist 

 of a single whorl of large inflated chambers, few in numbers, 

 and in consequence of the large chambers making a sharp turn 

 in the convolution, the septal lines are at very different 

 angles with regard to each other. These await further elucida- 

 tion. 



{?) Noclosinella, sp. — There are a few straight or slightly 

 curved nodosariform Foraminifera in the material which ha^^e 

 been provisionally referred to this genus. The test is rough, 

 apparently finely arenaceous, septation often obscure. Xone of 

 the examples appear to be in a perfect condition, and their 

 general features seem to indicate a closer relationship to the 

 Carboniferous genus above quoted rather than any other of 

 the Xodosariform group. Xodosinella has not been known 

 hitherto outside of the Carboniferous formation, in which some 

 of its specific forms are widely distributed. Better specimens
