BADIiAMIA.

BANGIA. 



scopic plants of tufted habit, growing upon 

 decaying wood, old bark, &c. ; 

 white at tiist, but coloured 

 subsequently by the condensa- 

 tion of the grunious contents 

 of the spores. Three species 

 are recorded as British : 



£. Jlavum, Kze.

BADHA'xMIA, Berk.— A genus of Myxo- 

 gastres (Gasteromycetous Fimgi), consisting 

 of little variously-coloured sacs growing in 

 patches on decayed oak-branches, &c. ; allied 

 to PItysarum, but remarkable for the spores, 

 at first enclosed in a common sac, adhering 

 in clusters. Filaments of the capilLitium 

 broad.

B.EOMY'CES, Pers.— A genus of Li- 

 chenaceous Lichens. 



The fom* species are found on the earth 

 and stones.

BAIRDIA, M'Coy. — A marine genus of 

 Bivahed Entomostraca, belonging to the 

 Ostracoda and related to the Cypridse. 

 First known \)j its valves alone, which are 

 subtriangular. Abundant, both recent and 

 fossil ; found also in the Palaeozoic rocks.

BALAXI'XUS, Germ.— A genus of Co- 

 leoptera, of the family Curcidionidae. 



B. nucum is well known as depositing its 

 eggs in nuts, upon which the larva lives, and 

 from which it escapes, leaving a hole. 



The beetle is 1-3" long, with a rostrum 

 nearly as long as the body. Laiwa white, 

 with a brown head and strong jaws,

BALANTID'IUM, CI. & L.— A genus 

 of Infusoria, fam. Bursarina. 



Like Kondyhstoma, but the body dilated 

 behind and narrowed in front. 



B. entozoon. In the human intestines, 

 and those of frogs. 



BiBL. CI. & Lachm. Infus. p. 227. 



BALSAM (Canada). The liquid resin of 

 the Pinus Bcdsamea. This is the ordinarily 

 used and best medium for the preservation 

 of dry transparent objects. The more co- 

 lourless it is, the better. It should be kept 

 in a wide-mouthed bottle, covered by a large 

 cap, fitted by grinding. A piece of iron-wire 

 should be kept in the bottle, so that the 

 desired quantity can be easily removed. It 

 becomes thicker by keeping, but may be 

 rendered thinner by mixture with oil of tur- 

 pentine and di<?estion at a gentle heat, or 

 with benzole, if too thin, it should be ex- 

 posed to a gentle heat in a bottle covered 

 with paper, to exclude dust. See Peeser- 



VATION. 



BALSA'MIA, Vittadini.— A genus of 

 Tuberacei (Ascomycetous Fungi), character- 

 ized by the hollows Avhich are lined by the 

 fructifying cells not leading to the sm'face, 

 and its cylindrical or oblongo-elliptic even 

 sporidia. 



Balsamia platyspora occurs in ditferent 

 parts of England, and is eagerly scratched 

 up by squirrels attracted by its strong scent.

BANGTA, Lyngb. — A genus of Porphy- 

 rete (Florideous Alga?), placed among the 

 L'lvese by most authors, but stated by M. 

 Thuret to be Florideous. Species marine, 

 forming purplish, brownish-green, or red 

 tufts of filaments, upon rocks and stones or 

 on the fronds of other Algae, from 1 to 4 

 inches long, or in B. eiliaris, only half a 

 line long. Harvey admits five, three of 

 them, however, as doubtful : 



B. fusco-ptirpurea, Dillw. Brownish 

 green or purple glossy, several inches long ; 

 near highwater mark. Phyc. Brit. t. 96 ; 

 Brit. Ak/fe, t. 25 C ; Eny. Bot., t. 2055 & 2085. 



B. eiliaris, Carm. Forming a minute 

 pink fringe on Zostera marina. 



B. ? ceramicolu, Lyngbye. Purplish rose. 

 On small Algte ; about 1" long. 



B. ? carnea, Dillw. Pale red tufts on 

 Confervse. 



B. ? eleyans, Chauv. Minute tufts 1'" or 

 2'" long, rose-red, parasitic on small Algae, 

 rare. Harv. Phyc. Brit. t. 246.
