From the examination of a " Dictyojjliyton " [tuherofrtim, Conrad] sent to 

 him by Professor Wakd, of Rochester, the author confirms the opinion of 

 WiiiTFiKLD and IIiNDE, that the fossil belongs to the sponges and regards it as 

 forming, with Pbotosponoia, a distinct family allied to Eupleotella.

The author records the occurrence of these sponges in the upper 

 Devonian sandstones of jeuraont, Brittany, and identifies certain of them with 

 the Dictyophyton tuberosimi, Conrad [^Ilydiioceras Barroisi\ Another species 

 is described as D. [^Dictyospon^ia^ Morini. It is suggested that these 8i>onge8 

 belong to the suborder Dictyonina, Zittel.

Department of the British Museum,, pp. 130-132, pi. xxviii, fig. 3. 



The author places the genus Dictyophyton among the Dictyonine 

 sponges, under the family Staurodermid^, and in immediate association with 

 Pkotospongia, Salter. The view is expressed that the nine species of 

 Dictyophyton described by Hall (1863), probably all belong io the species 

 D. tuberosum, Conrad, and that the Tetragonis [^Primnodictya] Fifeliensis, 

 F. Roemer, represents the same genus. A figure is given of a specimen from 

 Cohocton, N. Y., probably the normal form of the species from the Brown 

 hill colony. McCoy's species, Tetrar/onis Danhyi, is also described as 

 Dictyophyton Danbyi, and it is observed that an examination of the original 

 species of Tetragonis (73 Murchisoni, Eichwald) shows it to be closely 

 allied to Ischadites.

Describes and figures a Dictyosponge from the middle Devonian of 

 Gerolstein, under the name Dictyophyton Gerolsteinense. It is shown in the
