Brindisi ; and their composition of an organic formation and 

 of carbonate of lime may be demonstrated just as well as for 

 the coccoliths, Now^ if we compai'e the granular zone of the 

 coccoliths with the circlet of globules of the rhahdoliths, and the 

 central disk [medullar space) of the coccoliths^ as the matrix of 

 the globules J with the shaft of the rhabdoliths^ and consider that^ 

 as I believe I have shown^ the dorsal disk or covering piece of 

 the coccoliths is of but little importance^ we must recognize the 

 most intimate relationship between these calcareous organisms^ 

 notwithstanding their difference of form. To regard the rhab- 

 doliths as organs or form-constituents of the Bathybius-^xoio- 

 plasm we have not the least reason ; and thus, it seems to me, 

 the last doubt is removed, as to whether the coccoliths are 

 independent creatures. The two bodies remain no less interest- 

 ing than they did before, when the coccoliths passed merely 

 as the tokens of the mysterious Bathybius. The origin and 

 significance of this latter organic material are still far from 

 being explained. As I have already indicated, it seems to 

 me that the supposition that the Bathybius-^xoio^\?i&va. is the 

 residue of other low organic creatures must be completely 

 rejected. It is, however, no Protiston or Moneron in the sig- 

 nification now current, according to which all these simplest 

 organisms have a limitation in space and a development. A 

 living creature of unlimited extension is so strongly in contra- 

 diction to our present notions of life and organization, that our 

 conceptions and ideas must first adapt themselves to it. 



LI. — Notice of a new Species of Lizard (Eumeces albofascio- 

 latus)//'om North Australia. By Dr. A. Gonther, F.R.S. 



The British Museum has recently received from Mr. KrefFt a 

 specimen of a very large species of Eumeces from Northern 

 Australia, which appears to be undescribed and may be cha- 

 racterized thus : — 



Eumeces albofasciolatus. 



A supranasal shield is present, but on one side it is confluent 

 with the nasal behind the nostril ; the nostril itself is so large 

 as to be partly formed by the supranasal. 



The lower eyelid is scaly. Palate entirely toothless, the 

 palatal notch being considerably behind the level of the orbit. 



The single prajfrontal forms a suture with the rostral and 

 vertical, which is very long, as long as the occipitals together ; 

 a pair of anterior occipitals ; central occipital elongate ; occipi- 

 tals bordered behind by four large scales. Nine upper labials, 

 the two posterior low. Opening of the ear not denticulated.
