A. galapagensis, holotype; dorsal view of prosto- mium with branchial disposition. The eggs found in the gravid females are small, subcircular with a white central vessicle about one third of the length of an entire brownish egg. There are 17 thoracic setigers (14 uncinigers) and 13 to 15 abdominal uncinigers (14 in the holotype); (Fig. 1A). Prostomium indistinctly trilobed and slightly notched with no glandular ridges. Mouth bilobed, oral tentacles numerous, deciduous, ventrally grooved and re- tractile. Four pairs of finely annulated long branchiae (approximately 15 mm in holo- type), narrowly grooved ventrally, individually inserted across the dorsal surface.
