This form is probablv the same as E. elegans rar. Danica, Jacobs. Desm. 

 Danmk. p. 191, t. VII, f. 14. 



With reference to this species I would observe that manv of the sinn/ler forms 

 usuallv attributed to E. elegans, Bhéb., really belong to E. binale. The following may 

 belong to this species: 



Var. unicoriie, n. v. E. minus; semicellula? basi rotundatae, supra sinuatae, at- 

 tenuata 1 ; apicibus truncato-retusis, ad angulos utroque latere mucrone parvo munitis; 

 semicellulae centro tumida?, annulo granulorum ornatae. A latere visum ovato-lanceo- 

 latum, attenuatum, apice rotundatum; modice constrictum. 



Long. 24, lat. 15, lat. isth. 4.5 .«. T. X, f. 58 (also in Wallich Mscr. No. 201). 

 Hal), d. Northern India; a, b, c, and var. Bengal; c. also from East Bengal, ex 

 Utricularia flexuosa, comm. G. VON L. 



29. E. simplicius, n. sp. E. minus, circ. quinta parte longius quam latins; semicellulae in- 

 distincte hexagonae, lateribus sinuato-alatae plusquam lobata?; angulis basalibus rotun- 

 datis sub-acute protentis, apicalibus plus minus mucronatis sa?pe inermibus vel rectis; 

 semicellula? lateribus in superiore parte incavatis, apicibus cuneate fissis; utraque semi- 

 cellnla tumoribus apicalibus 2 parvis et basalibus 2 majoribus ornata; membrana re- 

 liqua laevi; sinu acuto, anguste cuneato. E. binali (Turp.) Ralfs proximum. 



Long. 30, lat, 24, lat. isth. 9.5 ,«. T. X, f. 31. 



f. minor. Long. 22, lat. 18, lat. isth. 5 n. T. X, f. 41. 



30. E. quintanum, n. sp. E. sub-mediocre, quarta parte longius quam latum; semicellula' 

 pyramidato-truncata^ (apicibus triangula riter fissis, leviter rotundatis, crenatis, angulis 

 rostratis), apicem versus contractae; lateribus tripliciter emarginatis. dentatis basali parte 

 ad fines rotundata etiam dente unico ai'mata; membrana glabra, sed tumoribus 5 (4 

 angularibus 1 centrali) ornata: sinu lineari, angustissimo, vix ampliatö. 



Long. 42, lat, 33, lat. isth. 7 ,u. T. X, f. 42. 



This is near to, but smaller than, E. /ärtnu) Börgesen (Desm. Brås. p. 939, t. II, 

 f. 19), in the lateral outlines it somewhat resembles it, but that form has 7 inflations 

 this only 5.
