the Nomenclature of the Foraminifera. 287 



Tertiary beds and alluvium of Damascus. We presume tliat 

 Dr. Elirenberg's specimen came from one of the upper white 

 limestones. 



(VIII.) PI. XXV. I. A. fig. 1. Miliola elongata^ a Lagena very- 

 similar to L. distoma^ P. & J., but more patulous at the extre- 

 mities. Figs. 2 & 3, Nodosaria procera^ 4, N. Icevis, 6, N. su- 

 hulata^ and, 6, N. turgescens^ are varieties of iV^. omc?*/a, D'Orb., 

 passing into a more compact form ; 3 & 6 =^. ovtcida] 2, 4, 

 & 5 have more closely set chambers, resembling N. Jdiformis, 

 D'Orb. ; 5, in particular, is a thick, coarse, rough shell. 

 Fig. 7, Frondicularia nodosaria^ is an attenuate simple Nodo- 

 saria of the radicuJa type (such as N. subnodosa, Reuss, 1851, 

 from Lemberg), with overlapping chambers*, which, seen in 

 section, have somewhat of a chevron-like aspect. Figs. 8, 

 Textilaria globidosa^ a, 9, T. glohulosa^ y. amjylior, 10, T. in- 

 flata^ and 11, T. globidosa^ 7. amijlior^ are T. globidosa^ Ehr., 

 the small arrested form belonging to T. gihhosa, D'Orb. 

 Figs. 12, Grammostomum suhacutum^ and 13, 2ext. globidosa{?) 

 are larger T. gibbosce, with a tendency towards T. aggluti- 

 nans. Fig. 14, Gram, spatiosum^ is a good Bolivina punctata. 

 Fig. 15, Gr. laxum (?), with its rather cloudy shell, is proba- 

 bly Virgulina Hemprichii (Ehr.). Figs. 16, Gr. polythecal 

 ("compare G. lateraW'')^ showing side views of its loop-like 

 apertures, 17, 18, Gr. caloglossa, and 19, 20, Gr. poIgtheca{?)j 

 all belong to Bolivina inmctata ; fig. 20 has a rather broad 

 shell, therein approaching B. dilatata\ fig. 21, Gr. costulatum^ 

 is a Bolivina^ near B. costata, gently sulcate, with pores in the 

 furrows. 



Fig. 22, Gram, micromega, is a piece of a large Textilaria 

 of the sagittula group, and fig. 23, (rr.? {Strophoco7ius?) lepto- 

 derina, seems to be its young form. Fig. 24, Gram, eurytheca^ 

 is Text, sagittula. Figs. 25 & 26, Bigenerina libanotica^ is 

 Polymorphina compressa. Figs. 27 & 28, Rotalia lialiotis, is 

 a thin-walled, thickly perforated Planorbidina farcta, with 

 rapidly increasing whorls and the last chamber much pro- 

 duced. Such are common in the Mediterranean. 



Figs. 29, Planulina stigma, 30, Globigerina libani (" com- 

 pare Gl. stellata''''), and 31, PI. pachyderma, show three suc- 

 cessive sizes of the typical Glob, cretacea, D'Orb. Fig. 32, 

 Plamdina argus, is Planorbulina farcta. Figs. 33, Planulina 

 monticulosa, and 34, Rotalia laxa, belong to a rough variety 

 of Planorb. farcta, granular and coarsely perforate. Figs. 35, 

 Rotalia protolepta, 36, Planulina saxipara, 37, PI. leiopentas, 



* Such is tlie main character of Ehrenberg's genus Encorycium, Mo- 

 natsber. for 1858, pp. 11 & 10.
