Also in Wallicii Mscr. Nos. 170 and 281. »Endochrome collected into 2 ir- 

 regular patches in each segment», G. C. W. These forms in front view are much like 

 C. Smolandicum Lundell (1. c, p. 38, t. II, f. 17), but the vertical view is more 

 aouminate and the lateral view not so deeply constricted as in Lundell's species. The 

 form b, supra, is either smooth or delicately punctate. c shows the mucous invest- 

 ment; this fig. is after Wallich. I certainly hold the opinion that these forms should 

 not continne under C. obsoletum, as the basal angles are aculeate not aeuminate. 



72. C. forte, n. sp. C. mediocre, circ. quarta parte longius quam latius, longe ovale, pro- 

 funde constrictum, sinn aperto, sub-lineari, externe parum aperto; semicellulae ferc 

 semicirculares, basi acuto-rotundatse ; membrana percrassa, 2 — 3 ju crassitudine, modice 

 punctata. Habitu fere C. }>achydenni, Klebs (I)esm. Ost. Pr. p. 34, 'a typicum, No. 3, 

 t. III, f. 36), non Lundellii (I)esm. Suec. p. 39, t. II, f. 15) nec Nordstedtii, v. minus,

The margin owing to the puncta appears striate; there are two amylum corpuseles 

 in each semicell.

73. C. rugosum, n. sp. C. mediocre, longitudine circ. I 1 s latius; rotundo-ovale; semicellulae 

 late ovales, angulis rotundatae, dorso leviter rotundatae, apice non dilatatae; sinu medi- 

 ocre, lineari, extrorsum ampliato; membrana rugosa, nodulis in series (13 — 14 rectas 

 verticales, et circ. 9 — 10 transversas) ordinatis; centro juxta isthmum laeve. A vertice 

 visum ovale.

Nearest to C. conspersum Kalks (Br. Desm. p. 101, t. XVI, f. 4) but although 

 the vertical x\u\v is much similar, the front view is very different, having broadlv- 

 rounded angles at base and the end, which is not dilated (as in C. conspersum) but 

 simply rotund. 



74. C. praecelsum, n. sp. Cos. submediocre, tam longum quam latum, circulare; semicellulaa 

 paullo dolabriformes, dorso rotundatae; (angulis inferioribus protractis, dejectis,) mar- 

 gine crenato-gemmulata'; sinu cuneato, extrorsum fere occluso \el constricto; membrana 

 verrucosa, nodulis ovalibus in series (6 laterales et 12 — 13 rectas verticales) ordinatis; 

 media parte frondis, juxta isthmum lasvi. A vertice et a latere non observata.

75. C. Sikhimense, n. sp. C. sub-mediocre, vix latius quam longum, a fronte bi-ovatum; 

 semicellube ovales, dorso leniter depressaj; lateribus angulato-rotundatis, e sinu cur- 

 vatis, margine integris; incisura mediana brevi, aperto, externe ampliato; membrana 

 sparse granulosa, apud marginem seriem nodulis conice-acutis (maximis apicem versus) 

 praädita. A latere visum modice constrictum, sinu rotundato, semicellulae fere glo- 

 bos;e.
