Series consists of 12 watercolour paintings of flowers by Elizabeth Gwillim, created while Gwillim was living in Chennai, India (then Madras). The paintings are preceded by pages of brief notes by Casey A. Wood. The flowers are identified by small caption titles written in pencil on each painting.

The series consists of 121 watercolour paintings of birds, created by Elizabeth Gwillim while she was living in Chennai, India (then Madras). The birds were painted from life rather than from the skins or stuffed specimens used by many artists of her day. Many paintings feature their avian subjects within a full landscape. Some paintings contain inscriptions with species identifications and, occasionally, additional observations about the birds.

The series consists of 31 watercolour paintings of fish, created while Elizabeth Gwillim and Mary Symonds were living in Madras, India (modern-day Chennai). The paintings are preceded by an introductory page of notes by Casey A. Wood. The paintings were originally attributed to Gwillim by Wood, largely on the basis of handwriting, but have more recently been tentatively attributed to Mary Symonds approximately around the year 1805 on the basis of information found in the sisters' correspondence. The fishes depicted are identified by a handwritten caption in the margin of each painting. Approximately one third of the paintings also feature an additional caption written in an Urdu script. These paintings may be copies of Symonds' originals created by a local artist in India. Item 30 (Crocodilus palustris) also contains additional manuscript notes.
