Viallanes [27, p. 66] describes the dorsal vessel of a young dipterous larva, which he refers to the genus Ctenophora, in which he observed tufts of fine tracheas in the pericardium, and the connection of the dorsal vessel with the transverse anasto- motic tracheal trunk. He adds : Fig. i8.—The dorsal vessel : /, a semi-diagrammatic representation of the two posterior sections, showing the large cells of the pericardial septum, the alse rnuscularcs and the cell fringes ; 2, the anterior eNtremity of the aorta and the ''g ; 3 transverse section of the intermediary portion ; 4, a longitudinal sec- tion of the same, with a pair of valves, seen from aljovc, sliowing the internal cells, cell fringes and aLx musculares ; 5, a lateral view of a valve pouch—[V o' immersion lens.
