cf. is an abbreviation from a Latin word (confer) and means 'refer to' or 'compare with', here it means it could possibly be Godiva rachelae or perhaps something closely related, or at least similar in appearance.
Godiva rachelae is characterized by a watery orange head with fine deeper orange speckling and a pair of bright orange lines on each side of the head. The area between each pair of lines is milky yellow. The oral tentacles are basally diffuse violet, followed by a broad whitish ring, followed by a broad diffuse violet ring, the outer third is white, these colours merge into each other. On each side, from just behind the oral tentacles, a band of milky yellow runs below the cerata to the posterior end of the body. Between each ceratal arch, this yellow band widens. The rest of the body is a pale, watery orange, with a series of white markings down the dorsal mid-line. The rhinophores are a watery orange colour with a yellow tip. The lower two thirds of the cerata are watery orange. The upper third is transparent, apart from the band of milky yellow just below the tip.
Godiva rachelae was described by Bill Rudman (1980) from specimens had collected in Dar es Salaam, Tanzania and at Broadhurst Reef, off Townsville, Queensland, Australia. The holotype is from Tanzania, that is the type localty is Dar es Salaam, Tanzania.
There are records (I doubt many identifications) of Godiva rachelae   Rudman, 1980 from:
-Okinawa, Japan,
-Caloundra, Queensland, Australia,
-Southwestern Indian Ocean,
-Bali - Indonesia,
-Milne Bay Province, Papua New Guinea
-East Timor
-United Arab Emirates
Though Bill Rudman (1980) writes on the Australien specimen "In all features this specimen agrees with East African material." All recent publications of DNA based researches have shown that species with a wide distribution are in fact at least 2 distinct species or even a species complex. This is the reason why I state:
The specimens from the Indian Ocean, because of the type localty Tanzania are the real Godiva rachelae  Rudman, 1980, and publish the picture of the specimen from the Philippines/Pacific Ocean at these websites as Godiva cf. rachelae  Rudman, 1980.
In the above specimen are the orange lines on the head absent/very hard to see, the rhinophores and the cerata differ from the description.
