There is nopatagial fan, but a specialslip, found in all the othermembers of the family (andalso occurring in Lanixargent at us), runs from thelongus tendon to the op-posite side of the fore armto that upon which thepatagial fan, when present,is inserted. In Bracliyrliampliusmarmora tus three separateand parallel tendons arise.

From a smallwristward slip arise a few fibres of the extensor metacarpi, asin the last species. There is no patagial fan, but an ulnar slip,which gives off a branch running back to the humerus. InUria columba there is the same. In Lunda cirrhata there are but slight differences; thetwo most anterior of the brevis tendons cross the extensor 1 Not figured at all by GARROD in a MS. sketch. - For various details in anatomy of soft parts see BEDDARD, On the Anatomyof a Grebe (JEclimopliorus ii/rijor), with Remarks upon the Classification ofsome of the Schizognathous Birds, P.
