TitlePaper, 'On the vertebral chain of birds' by William Kitchen Parker
DescriptionParker writes: 'A few years ago I noticed a remarkable fact in the development of the Green Turtle (Chelone viridis), namely, that whilst thirteen myotomes are developed in the cervical region, the intercalary vertebral segments found afterwards are only eight. More recently, whilst working out the development of the vertebræ in various types of Birds, it struck me that we have in these high forms creatures in which the vertebral chain has been greatly shortened daring their secular development. It seems to me to he probable that the Amphibian stock from which birds arose—becoming Reptiles in their ascent, but spurning that intermediate stage—were long, eel-like forms, not dissimilar to Amphiuma and Menobranchus among the existing Urodeles.'
