Zoology. 79 
In one of the numerous ichthyological papers emanating from 
the Indiana University, Carl H. Eigenmann and Eliz. G. Hughes 
give a review of the North American species of the genera Lago- 
don, Archosargus and Diplodus. The first has one species, while 
the second and third are represented in North America by four and 
seven species respectively. Mr. Eigenmann also describes Ophich- 
thys retropinnis, from Pensacola, Fla. 
Miss Rosa Smith bases a new species of Rhinoptera upon a pair 
of jaws found at Todos Santos Bay, Lower California. 
BATRACHIA AND REPTILIA.—G. B. Howes (P. Z.S., June 7,1887) 
points out the existence, in the larynx of some Salientia, of a struc- 
ture which he believes to be homologous with the epiglottis of the 
higher Amniota. These are in the form of two papil'ate folds, 
constituting a forward prolongation of the laryngeal mucous mem- 
rane. Posterior to these some Anura have also a pair of folds, 
which Mr. Howes entitles epilaryngeal. The epiglottis is entirely 
membranous, and has little if any connection with deglutition. It 
seems to be purely an accessory voice organ. The Batrachian lar- 
ynx, like the Reptilian, is without a distinct thyroid cartilage. The 
author gives a list of the species in which the primitive epiglottis, 
the paired condition of which resembles the initial stage of the 
development of the organ in the human subject, was observed. 
Some species of Hyla are without the folds, while they are present 
in others. 
The Bulletin of the Essex Institute, 1887, contains descriptions 
by Mr. S. W. Garman of the Iguanide and Scincide of the West 
Indies, at present in the Museum of Comparative Zoology at Cam- 
bridge. No less than twelve species are added to the genus Anolis, 
each species apparently restricted to a small cirea. The scincoid 
genus Mabuia is also enriched with three new species. 
Mr. Garman has also published a list of the Reptiles and Batra- 
chians of Grand Cayman, an island of the Caribbean Sea, about 
200 miles south of Cuba. Grand Cayman is of coral formation, 
rises but little above the sea, and must have received its land ani- 
mals from the neighboring islands not so very long ago. An 
Anolis and a Liocephalus are described as new. 
Mr. Garman has recently added to the snakes of the West Indies 
Ungualia curta, Dromicus cubensis, and D. ornatus, Alsophis pul- 
cher, and Trigonocephalus caribbæus. A small turtle, Cinosternum 
Sp., sent to Cambridge by Professor F. Poey, seems to possess dis- 
tinct specific characters.
