acute an observer as Dr. Prout should have overlooked the characters 

 of Prof. King's genus Synodadia. Our Scotch form and S. ces- 

 tricnsis, Prout, agree very closely, so far as I can judge from descrip- 

 tions and figures, and appear to differ only in a much greater irregu- 

 larity of branching in the case ofS. carbonaria, and also in its having, 

 as in Synodadia, the cell-apertures arranged in two rows on the in- 

 terstices. Dr. Prout's figure docs not give a good idea of this peculiar 

 polyzoou ; but I have been favoured by Prof. King with extracts and 

 photographs from a letter to himself from Mr. F. B. Meek, of Spring- 

 field, Illinois, regarding the question of Septopor-a and Synodadia. 

 These photographs show that the American specimens are in a much 

 better state of preservation than the Scotch ; and although the 

 points of difference between the two are slight, I think they are of 

 sufiicient importance to warrant a specific separation ; however, 

 should Mr. Meek have previously elsewhere described any form 

 nearer S. carbonaria than Septopora cestriensis, my designation can 

 give place to his ; in the mean time I retain for the Scotch fossil 

 the name of S. carbonaria. Mr. Meek status that fuller descriptions 

 and figures will be given in the forthcoming fifth volume of the 

 ' Geological Survey of Illinois.'

Japan? [Fortune). Possibly from North China, as Mr. 

 Fortune's collections from the two countries were mixed to- 

 gether when I saw them. 



Elytra more eKmgate than in the same sex of T. meridianus, 

 and of quite different shape, being broad and rectangular at 

 the base, then slightly narrowing to beyond the middle, and 

 widening again before the apex ; the wliole surface roughly, 

 but not veiy coarsely, scidpturcd. The thorax is much more 

 strongly tuberculated, glabrous on the disk ; there are two 

 strong rounded tubercles on each side the median sulcus, and
