Genus TOLYPAMMINA Rhumbler, 1895. 



TOLYPAMMINA HORRmA, new species. 



Plate 74, fig. 5. 



Description. — Test attached, under surface made up of a subglobular 

 proloculum and elongate-cylindrical chamber; wall consisting of fine 

 sponge spicules radiating from the surface ; wall inside smoothly fin- 

 ished; aperture formed by the open end of the tube. This species 

 resembles Saccorliiza ramosa H. B. Brady in the spicular character 

 of the test, but is attached throughout its length, and has a sub- 

 globular proloculum, whereas typical T. vagans H. B. Brady has a 

 smooth wall and elongate proloculum and is a much smaller species. 

 The tubular portion of this species measures one-third mm. or more in 

 diameter. 



This seems to be a common species of the material. Four speci- 

 mens are mounted and attached to shell fragments, all uniform in 

 character. There is a specimen in Sidebottom's material^ "almost 

 white in color and attached to a fragment of a shell." This also may 

 be the same as this species.

There is a single specimen which may be referred to this species, 

 but it is not typical. It consists of what seems to be a double- 

 chambered proloculum with the tubular portion broken away. 



Subfamily Ammodiscinae. 



Genus AMMODISCUS Reuss, 1861. 



AMMODISCUS MESTAYERI, new species. 



Plate 74, figs. 1, 2. 



Description.— H&st large, in the microspheric form consisting of an 

 elongate ovoid proloculum with three or four coils; central portion 

 depressed; megalospheric form with large subglobular proloculum 

 followed by one and one-half coils; test thickest in the central por- 

 tion; wall composed of fine angular sand grains with whitish or light 

 brown cement; exterior smoothly finished. 



Diameter. — Microspheric, 4.5 mm.; megalospheric form, 2.5 mm. 

 The proloculum of the megalospheric form is nearly 1 mm. in length, 

 and of the microspheric about one-fourth that size.
