| Description | Watercolour drawings of Steller's 'sea cow' Rhytina gigas (Zimmerman, 1780). Drawing of the horny corrugated layer of hardened epithelium which covered the palatine surface of the premaxillary bones and served in lieu of teeth for chewing the seeds on which this animal fed, copied from Brandt's 'Symbolae Sirenologicae', St. Petersburg, 1849; ideal restoration (one twntieth natural size) of the form of Rhytina gigas, Zimm. Copied from Brandt's figure in his 'Symbolae Sirenologicae'. Descriptive information taken from the labels attached to the drawings. The drawings appear to have accompanied specimens on display in a case. |
