NATURAL SCIENCES OF PHILADELPHIA. 123 



Quite conspicuous, not elevated maculae are distributed over the surface. 

 Locality. La Grange, Missouri. (Keokuk Limestone.) 



FlSTDLIPORA COMPRESSA nOV. Spec. 



Occurs associated with the former. 



It grows in compressed ramose stems about one centimeter wide in the 

 larger diameter, which are fixed to the ground or to foreign bodies by an 

 irregular basal expansion. Surface raised in obtuse, unequal monticules, 

 with a cellulose macula in the centre of each. Tubes one-sixth of a milli- 

 meter wide, of irregular form, distant about a tube diameter or less, and, if 

 the surface is not worn, surrounded by an elevated margin. Structure in 

 conformity with all the other Fistuliporas. 



Fistclipora peculiaris nov. spec. 



Is a very interesting representative of stellate or floriform tube orifices in 

 Fistulipora, with whose occurrence in the genera Chaetetes and Collopora we 

 have already become acquainted. It grows in thin leaf- like expansious, with 

 orifices on both sides, or in simple leaves with an epitheca below. Orifices 

 circular, surrounded by an equally-projecting margin, distant more than their 

 own diameter, and exhibiting from six to ten tooth like projections from their 

 inner circumference. By grinding away the superficial portions, the tubules 

 appear still provided with these radial dents, an evidence that they are not 

 gpinulose projections confined to the tube margins, but the euds of vertical 

 ridges, running through the whole length of the tubules. 



The surface is dotted with scarcely-elevated cellulose macuhc, which, like 

 the narrower intertubular spaces, are finely granulose. Intertubular tissue 

 vesiculose. Tubules rarely septate. 



Locality. La Grange, Mo. (Keokuk Limestone.)

Chelopus areolatus? Cope, Proc. 1. c. 1865, 186. Emys areolatus Dume'ril, 

 Arch. d. Mus., vi. 223. 

 A large female specimen from Belize, from Dr. Parsons, confirms the characters 

 of that from the expedition, and appears to be distinct from the C. punctu-

Anolis nebulosus Wiegmann. 



One sp. No. 714. Very near the true A. sallaei Gthr. 



Anolis laeviventris Wiegm. 



This species is allied to Schiedii Wiegm. (serice.us Hallow.) and t r o p i- 

 dogaster Hallow. Several specimens Nos. 503, 505, 452. 



Basiliscus vittatus. Corytkaeolus Kaup. 



Abundant. A second specimen of the allied B. nuchalis Cope, Proc. 

 A. N. S. Philada., 1862, 181, has been sent to the Museum Smithsonian by 

 Robt. Kennicott, from Panama. The B. galeritusA. Dum. is the species 

 since described by Gray as B. (Ptenosaura) seemanni.
