venture to offer an opinion with any approach to certainty. The Dianaa cerebriformis of 

 plate X IS possibly a Cyantea. The EudortB are evidently mutilated disks.

Dr. Baird, in an interesting paper « On the Luminousness of the Sea," figures a small 

 Medusa [Geryonia ?) from the Straits of Banca : the figure and notes are insufficient. 



1831. 'Magazine of Natural History/ vol. iv, p. 285. 



In a note on the " Luminosity of the Sea/' by Mr. Samuel Woodward, a very minute 

 Medusa of this order is figured from specimens taken between Lowestoft and Yarmouth. 

 The figure represents either a young Sarsia or the medusoid of Tubularia.

 d'Urville.) 



The Medusse are described in the fourth volume of the text, and figured in plate xxv. They 

 are Carybdea bicolor, possibly an imperfect animal, but well figured; Carybdea bitentaculata, 

 and a covered-eyed species, Orythia incolor. Of the two former, the first was found near 

 the Cape de Verde, the second, in the roads of Amboyna.

The account of the pulmograda in this useful manual is a very full and excellent compilation 

 of the knowledge up to the time, and amoug the plates are many useful figures copied 

 from other works. De Blainville combines the genera ^guorea, Mesonema, Polyxenia, 

 JEffina, and Cunina in one genus, jEquorea. He refers Melicerta penicellata of 

 Eschscholtz to the genus Aglaura of Peron. Under Geryonia he unites Saphenia, 

 Geryonia, and Diantea proper ; regarding Dianaea endractensis as the type of that genus.
