NOTICE OF UNDESCRIBED ZOOPHYTES 



appearance : neither the stem, nor the side arms appear to 

 have had any central perforation. The original is nearly six 

 inches in length. 



2. Sp.fastigiata. — The lower part funnel-shaped, inflated ; the upper 

 part a cone, rising from a slight depression. Fig. 8. 



This fossil is not by any means common ; 

 I have only seen two specimens, of which 

 the most perfect is represented in the 

 annexed sketch, {fig. 8.) The inferior 

 part is surrounded by depressed undula- 

 ted lines, some of which take a diagonal 

 direction : the terminating cone is small, 

 and not by any means proportionate to 

 the inflated appearance of the lower part : 

 the central cavity appears to be very 

 small indeed. 



The figure is about one half the natural 

 size. 



Sp. sepiaformis. — Irregularly funnel-shaped : marked externally with 

 a few scattered elevated orifices ; from eight to ten arms, rising up- 

 wards from the superior edge : one or more additional branches arising 

 from the same root. Fig. 9. 



This beautiful species appears to 

 be extremely rare: besides the 

 specimen represented by the fi- 

 gure, {Jig. 9.) I have only met 

 with two or three fragments, 

 which still were sufficient to con- 

 vince me that the above charac- 

 ters were not accidental : the 

 length of the fossil from the root 

 to the extremity of what remains 

 of the longest arm, is about eight 

 inches : there is an appearance of 

 I |fc : ^M one small side arm, thrown off 



i ■iffi|ffi downwards, but most probably 



JfH/' this is not a constant character : 



the root does not appear to have 

 been very fibrous.
