At the meeting of the Linnean Society on April 21st, Prof. 

 Douglas Campbell communicated a paper, which was demonstrated 

 by Mr. A. Gepp, F.L.S., "On the Structure of Dendroceros.'' The 

 chief conclusions arrived at were as follows: — (1) In its apical 

 growth and the form of the thallus, Dendroceros differs decidedly 

 from other genera of the order Hepaticae. The type of apical cell 

 is that found in Pellia epiphylla and in the homosporous Ferns, 

 especially Osmunda, where the prothallium resembles the thallus of 

 Dendroceros also in the definite midrib and the occasional develop- 

 ment of leaf-like lobes. (2) The archegonium corresponds in its 

 structure to that of the other Anthocerotacem, and is intermediate in 

 character between Notothylas and Anthoceros. (3) The antheridium 

 is solitary, and arises, as in the others of the order, endogenously. 

 (4) The first wall in the embryo is longitudinal, as in Anthoceros, 

 but the first transverse wall determines the limits of the foot, as in 

 Notothylas. (5) The origin of the archesporium is from the amphi- 

 thecium, as in the other genera, but it is less massive than in either 

 of these. (6) The division of the archesporial cells into sporogenous 

 and sterile ones is less regular than in either of the other genera,
