It remains to be seen whether our species is rehited to the JEquo- 

 rea violacea of Milne-Edwards, well described and beautifully figured 

 in the 16th volume of the 2nd series of the 'Annales des Sciences 

 Naturelles,' and observed by that eminent naturalist in the Mediter- 

 ranean. From an examination of its anatomy he first showed the 

 serious error committed by Eschscholtz in considering the JEquorid(B 

 as cryptocarpous. I am inclined to agree with Milne-Edwards in 

 considering his species distinct from that of Forskal. The genital 

 glands are not prolonged nearly so close to the margin ; the lips of 

 the stomach are not furbelowed ; the bases of the tentacles are not 

 bulbous, and originate regularly between the gastro-vascular canals. 



There were no eyes observed by the distinguished zoologist just 

 quoted in the species he examined- In ours the eyes are evident, 

 and a determination of their position and appearance is of conse- 

 quence, since they confirm the affinity of JEquorea with the Naked- 

 eyed Medusae, whilst at the same time, in the little appendage or 

 rudimentary lid projecting above them, they indicate an approach to 

 the Steganophthalmatous type, such as is consistent with the general 

 high organization and aspect of the Mquorea when compared with 

 other Gymnophthahiatous forms. 



It is interesting to rem.ark that the jEquorea ciliata of Eschscholtz 

 is a North Pacific species, beautifully representing, yet quite distinct 

 from, Mquorea Forskalea.

 On some Bones of Didus. By A. D. Bartlett. 



The history of the Dodo having been recently the subject of so 

 much inquiry, and the exertions made by Mr. Strickland, Dr. Mel- 

 ville and others, having succeeded in bringing together so many 

 important facts, it might appear that there was little more to be said 

 upon the subject ; this, however, I believe is far from being the case. 

 A few facts established upon a subject which was before obscured in 

 doubt and error will, I trust, always act as a charm, and induce us at 

 every opportunity to investigate that subject still further, in the hope 

 of learning the truth. On the present occasion I am desirous of call- 

 ing attention to a few bones upon the table. In so doing I beg to 

 say, that in the year 1830 a collection of bones arrived in Paris, which 

 attracted the attention of the scientific world. These bones came 

 from the island of Rodriguez, but on account of their being incrusted 

 with stalagmite, little has been done with them ; they were, however, 

 the cause of search being made for more in the same locality, and two 

 collections were made in the year 1831 by the late Mr. Telfair. One 

 of these collections was forwarded to the Andersonian Museum in 

 Glasgow, the other to the collection of this Society, and at the even- 

 ing meeting, March 12, 1833, the bones sent by Mr. Telfair were 

 laid upon the table. 



I will here read an extract from the Society's Proceedings : — "Dr, 

 Grant pointed out that they were the bones of the hinder extremity 

 of a large bird, and the head of a humerus. With reference to the
