Qth Novemler, 1871. 



Dr. Frazer exhibited seven well-crystallized diamonds from 

 Natal ; he directed notice to the peculiar brown colouring matter 

 which tinged portions of the edges of two of these diamonds, and 

 especially to black imbedded material not of crystalline form 

 situated deeply within two of the larger crystals ; this appeared 

 to be a variety of graphite, or allied to the bituminous substance 

 found in quartz. 



Rev. E. O'Meara brought forward some examples of British 

 Amphorae, stating his opinion that there existed three distinct 

 forms, but that they were erroneously confounded ; he was work- 

 ing up the whole subject, and ttie views he now propounded would 

 hereafter make their appearance in detail. 



Mr. Woodworth showed a number of elegant micro-photographs 

 by Colonel Woodward, aud sent to him from America by that 

 gentleman. Mr. Woodworth promised to bring before the Club 

 on a future occasion some details of the process as adopted 

 by himself. 



Dr. E. Perceval Wright exhibited a series of the calcareous 

 plates met with in the form of rosettes at the base of the ambu- 

 lacral feet, also of those found in the delicate ovarian mem- 

 branes of Echlnoneus minor, and the two forms of Pedicellariae 

 met with on the external ambulacral region of the same species. 

 He referred to M. Edmond Perrier's researches on the Pedicel- 

 lariae and Ambulacra of the 8ea Urchins, and regretted that 

 the author had not better worked out the literature of the 

 subject, for, although his memoir is of decided value, it would 

 have been much more so had the labours of his predecessors 

 been alluded to. Among the writers entirely overlooked, might 

 be mentioned Gaudry and C. Stewart ; the result of the investi- 

 gations of this latter worker Dr. E. P. AVright had laid some years 

 ago before the Club. M. Perrier gives a long list of the Echi- 

 noida that had been examined by him, including all the species in 

 the Zoological Museum of the Jardin des Plantes, and in his 

 ' Memoir' he mentions that he had never met with specimens of 

 the remarkable genus Echinoneus having spines, and so was unable 

 to determine whether they possessed PedicellaricB or not. In a 

 supplementary note he adds some details of these structures, as 

 met with in a species of this genus undetermined, and from an 

 unknown locality. From the description given in the note, it is 

 not easy to determine the species, but it is apparently not the E. 

 mino7', Lesk. All the species of this genus are very rare in a 

 perfect condition, so rare that very few museums or collections 

 possess even solitary examples ; hence, there is some interest in 

 having a detailed account of the calcareous skeleton of that spe- 

 cies, with minute description of all the calcareous appendages to 

 the corona. Into the supposed uses of the Pedicellariae Dr. E. P.
