 Supra lioc stratum basale surgit placenta magna oblonga ro- 

 tundata, plurimis cellulis contoxta (Ay. tah. XXXIILf,g. 20). 

 In inferiore j)arte placentse cellulas rotundato-angulatas, en- 

 dochromate sub-granuloso farctas, vidi; inter has cellulas 

 meatus intercellulares dilatatos, endochromate magis homo- 

 geneo C[uasi liquido impletos (Ay. tah. XXXIII. fg. 26 a). 

 Meatus hi intercellulares non tantum spatiis tri-tetracdris, 

 apicibus protractis, constare adparent — ut plerumque ob- 

 veniant — ; sed ssepe sunt dilatati et inter se evideutius con- 

 fluontes (Ag. tah. XXXIII. Jig. 28, infcrm). Jodio adposito 

 endochromata in celhilis strati basahs colorem luteo-fuscontom 

 assumserunt; in meatubus intercelhihiribus fit dilute hiteum; 

 in celluhs placentaribus inferioribus fere in coeruleum tendit. 

 Hoc modo meatus interceUulares quasi systema proprium ofh- 

 cerc facile crederes. Extrorsum et sursum ceUulse placenta- 

 res sensim prolongantur ot evidentius in hla ramosa al)eunt, 

 a quibus demum lihi proprie gemmidiifera radiantia exeunt 

 (Ag. 1. c. fig. 28). 



His indicare vohii totum adparatum placontarem esse et

 evohitum; omnibus vero characteristica videntur gemmidia 

 elongata pyriformia aut ol)Ovata, qua3 in articulis terniinali- 

 bus lilorum singula evolvuntur (Ag. tah. XXXII. fig. 27; tah. 

 XXXIII. fig. 13, 19, 28). Articulo terminah effoeto, ex ar- 

 ticulo penultimo singuli novi articuh gemmidiiferi formantur, 

 aut ssepe, ni fallor, plures ex eodeni evolvuntur terminales 

 et gemmidiiferi. Ssepius endochroma in his celluhs ponulti- 

 mis antea in partes subdivisum vidi, quasi in novos articulos 

 aut nova fila partes singulse abirent (Ag. fah. XXXII. fig. 27; 

 tah. XXXIII. fig. 28). Sub hac progredicnte evolutiono fila 

 gemmidiifera in mnltis elongantnr et novis ramis succrescunt "''');
