744 . EDWARD T. BROWNE. 



Order Physophorae, Eschscholtz, 1829. 

 Family Agalniidae. 



Genus Agalmopsis, Sars, 1846. 



There is only one specimen. It is badly contracted and has lost all the nectophores and 

 bracts. The tricornuate tentilla are large. I have not been able to identify the species. Bedot 

 has found Agalmopsis sarsi off the Amboina Islands. 



Family Physalidae, Brandt, 1835. 

 Physalia utnculus, Eschscholtz, 1829. 



Physalia utriculus, Huxley (1859, p. 101, PI. X., PL XII. fig. 12). 



About two dozen specimens in the collection. The float of the smallest specimen is about 

 4 mm. in length and 2 mm. in depth. It has one tentacle and a few siphons and palpons. 

 A specimen with a float measuring 8 mm. in length and 4 mm. in depth has a crest on the 

 top of the float and a few internal transverse septa ; one main tentacle and one secondary 

 tentacle much smaller in size ; several siphons and palpons ; and the gonophores just beginning 

 to develop. The largest specimens are about 20 — 25 mm. in length and 15^20 mm. in depth 

 and have one main tentacle and several secondary tentacles. Numerous siphons and palpons. 

 The gonophores are fairly well advanced in development. These large specimens resemble 

 Huxley's figure of Physalia utnculus. 



Distribution. Tropical and Pacific and Indian Oceans (Huxley). Maldive Is., Minikoi. 

 Laccadive Is. (Gardiner). 



Family Velellidae, Eschscholtz, 1829. 



Genus Velella, Lamarck, 1819. 



The collection contains a single small specimen about 13 mm. in length having a 

 triangular sail about 7 mm. in height. The tentacles are arranged in a single row round 

 the margin of the umbrella. The gonophores are beginning to develop on the gonostyles. 

 The specimen from its size and the appearance of the gonophores is an intermediate stage. 

 Until the Velellidae have been revised it is impossible to identify an intermediate stage. 



University College, London, 22nd April, 1904. 



A paper by H. B. Bigelow on " Medusae from the Maldive Islands," published in the 

 Bulletin of the Museum of Comparative Zoology at Harvard College (Vol. xxxix. No. 9, 

 April, 1904) arrived in London whilst I was revising the proofs of my paper. The author, 

 along with Prof A. Agassiz, visited the Maldive Islands during the months of December, 1901 

 and January, 1902. Special attention was given to the Medusae and the drawings of the 

 species were made from life. The list of Hydromedusae contains 22 species, eleven of which 

 are described and figured as new species. Not one of the species, which I have described 

 as new, was taken during this expedition.
