Si>(>id('.vst (ivjt'ctcd): Synonyiii loi- spore. Knii)loyed by Pl'eiHer.' 



Spoi(»i»lasin : Tlx* " ])()sterioi' mass,"' ''plasmic mass," etc., of the s])<)re. 

 This term is used as the eqnivaleut of the phrase "protoplasm of the 

 spore." 



Surface, inferior: Tliat upon whicli tlie inferior valve (</. v.) and the 

 infero-median (;ornu are situated (see also next). 



Surface. su])erior: That upon wliicli the sup(M'ior valve {q. v.) and the 

 supero-median cornu are situated. 



These are, respectively, the equivalent of dorsal and ventral, or of 

 ventral and dorsal. In the absence of Inenuil and nervous systems and 

 of an alinuMitary tract, the proper correlation of these surfaces with 

 the corresi)onding ones in extra-myxosporidiau organisms seeins impos- 

 sible. Inter .s'c, however, the superior surfaces may be correlated by a 

 greater convexity of the superior valve, but probably most frequently 

 by thii further projection for trard of the supcro-medlan cornu, which may 

 ( ■?) even reach the extreme anterior end of the shell cavity. 



Valve: Each shell half. 



Valve, inferior: The less (;onvex valve; see also next. 



Valve, superior : The more convex valve. The differentiation is prob- 

 ably possible in only a few cases. The supero-median cornu will 

 probably form a better guide to the dis(;rimination of the superior and 

 inferior surfaces 



VieAV, longitudinal, transverse, or vertical ; view along the line of 

 the corresponding diameter {q. v.).
