 dans le detroit de Gibralter.' 

 In this valuable paper a number of radiate animals, chiefly pelagic, are described, and among 

 them several naked-eyed Medusae. The species are all figured, though mostly with few 

 or no anatomical details. 



1. Diancsa rotunda, p. 181, pi. vi. A, figs. 1 and 3. 



Judging from the view given of the peduncle, this appears to be a true Oceania, with a globular 

 umbrella and eight marginal tentacula. 



2. Diancea conica, p. 182, pi. 6, A, figs. 3 and 4. 



The form of the body indicates a Circe, but the appearance of the peduncle is nearer that of 

 Oceania, and the remark of the describers, that it approaches the Medusa {Oceania) pileata 

 of Forskal, would confirm such a view. The umbrella is mitrate, and acute above. The margin 

 appears to have twenty tentacula, with red ocelli. The peduncle is reddish. 



3. Diancea exigua, p. 183, pi. vi. A, figs. 5 and 6. 



A small Geryonia, with very smaU cordate ovaries, and four marginal tentacula. 



4. Diancea exigua, Var., p. 183, pi. vi, A, figs. 7 and 8. 



Exactly like the last, but wanting the ovaries. Is this a male animal, or is it a Tima ? It is 

 the Liriopa cerasiformis of Lesson (Acal. p. 332), who strangely associates it with Diancea 

 proboscidalis, in his genus Liriopa, 



5. Diancsa hitentaculata, p. 184, pi. 6, A, fig. 9. 



A minute Geryonia or Tima, having two long tentacles and twelve short ones. This is the 

 Saphenia hitentaculata of Lesson. 



6. Dianma funeraria, p. 184, pi. vi. A, figs. 10-15. 



This appears to belong to a genus closely allied to Circe, and is certainly a member of the family 

 CirceadcE. It is the Tholus funerarius of Lesson. 



7. JEquorea capillata, p. 185, pi. vi, B, fig. 1. 



Too imperfectly described and figured to be assigned to any well-defined genus with certainty. 



8. Phorcynia pileata, p. 186, pi. vi, C, fig. 1. 



A mutilated or badly-observed species, of what genus ? It is the type of Lesson's genus 

 Pileola. 



1828. Dr. Fleming. ' History of British Animals.' 



Under the genus Geryonia are enumerated " G. cequorea," " G. hemisphcerica" [Thaumantias), 

 and " G, octona" [Oceania). The last previously described by Dr. Fleming, in the eighth 

 volume of the ' Edinburgh Philosophical Journal/ 



1829. F. Eschscholtz. ' System der Acalephen.' 4to, Berlin. 



A standard work upon this class, founded on extensive personal research. I have already 

 commented on the errors of the classification. The illustrative figures are in outline, 

 but strikingly faithful, so far as they go. The naked-eyed species represented are Melicertum 

 penicillatum ; Eurybia exigua ; Tima flavilabris ; Cyteeis tetrastyla ; Cunina campanulata 

 and globosa ; jEquorea ciliata ; Polyxenia cyanostylis ; j^quorea globosa (a Stomo- 

 brachium ?) ; jEgina rosea, and citrcea ; Mesonema abbreviata ; Geryonia bicolor and rosacea. 

 The descriptions are in German, each prefaced by a Latin diagnosis, too slight in most 

 instances to serve the purpose of identification. No student of the Medusae should be 

 without this book. 



1830. Lesson. 'Zoology of the Voyage of the Coquille' (under Duperrey). 



Most of the figures of Medusae in this work represent covered-eyed species. In plate xiv of 

 the Zoophytes, a few naked-eyed species are represented, but though the plates are 

 beautifully engraved and coloured, the original drawings must have been sadly defective, 

 judging from the Cyanma Bougainvillii {Bougainvillea Macloviana), the first that attracts 

 our notice, every organ of which is misunderstood, and wrongly delineated. Fig. 4 of 

 the same plate represents a Turris, under the name oi^Equorea mitra ; the peduncle and 

 ovaries strangely misunderstood. Fig. 1. Bursarius Cy therm may be a naked-eyed form, 

 but after the manner in which the two previously-cited species are represented, I cannot
