Bryce's Halgerda
Halgerda brycei
Halgerda brycei has translucent white large, sparsely pinnate gills which are lined with black. The rhinophore clubs are black and there is a line of black specks up the posterior midline of the rhinophore stalks.This species is named after Clay Bryce of the Western Australian Museum
Morphology
Halgerda brycei is similar to H. carlsoni with large, orange-tipped tubercles covering the dorsum, but H. brycei lacks the small spots between the tubercles. In fact there are no other orange markings on the mantle. It also differs from another similarly coloured species, H. batangas, which has a fine, orange network between the orange-tipped tubercles. Halgerda carlsoni lacks this dark line and H. batangas has dark spots on the anterior of the rhinophores. Another similar species, H. stricklandi has a yellow rhinophore club with similar orange tubercles on the dorsum.
