. The eyelids and lachrymal apparatus of birds [microform]. Oiseaux; Vision; Vision; Birds. Efelidt and Lachrymal Apparatus of Birds. 11 In the study made by Slonaker and the writer on the eye of tho Sparrow and other Birds they found Slonaker's marginal plait (see cut) not only in numerous sections of the Sparrow's third lid, but in all the other Birds so far examined; it is certainly well marked in such unrelated species as the Sooty Tern, the Red-Headed Wood- peclcr, and in various Pigeons. Strange to say, Fumagalli (Ueber die feinere Anatomic des dritten Augenlides, Intertiaiional. lion- atstchr. fiir Anatomie und Physiologie, Vol. 16, p. 189, 1899) makes no mention of this important structure, and, although the whole subject is by him elaborately illustrated by well executed Ldo. I the work of FumasalH, the lower i plates, he pictures the Pigeon's accessory eyelid as lacking in the marginal plait. All vertebrates possess at leaut six extraocular, bulbar muscles- four recti and two obliques. Birds have two more (that control the movements of the third eyelid) viz.: the quadratus muscle and the pgramidalis, which are inserted into the posterior hemisphere, bo- hind the scleral insertion of the recti muscles. Confirming the observations of Kalt (Encyclopidie francaise d'Ophtalmologie, Vol. Ill) and others, Slonaker and the writer.
