Janolus
sp. #1

 
Janolus sp. #1
Maximum size:  12 mm.

Identification:  The one collected animal autotomized many of its cerata and began to deteriorate before it could be photographed. The following is a slightly cleaned up transcription of the original notes: background color translucent brown; white frosting on the midline of the notum and on the caruncle; a diamond-shaped reddish-purple patch on top of the head; rhinophores heavily papillate with elongate, downward-pointing papillae on their lower portions (like candle-drippings); cerata nearly transparent; cerata "double pyramid-shaped", e.g., narrow at the base and tip with a broad middle and more or less flattened sides (4?); surface of cerata slightly lumpy; cerata with a noticeable "shelf" at the widest point; shelf with a narrow band of fine, internal white lines that form a "snake skin-like" filigree; a faint white spot at the tips of the cerata.

Natural history:  Two Janolus sp. #1 were found together under a rock at 5-7 m (16-23 ft). The site was moderately exposed.

Distribution:  Maui.

Taxonomic notes:  First recorded in Hawaii at Honokohau, Maui by CP on Aug. 4, 1994.
