Are these juveniles of Chromodoris verrieri??

I have found these 4 tiny (+- 4mm) nudibranchs in Yap in about 15m of water.

Locality: Goofnuw Channel, Yap Is. Pacific. Depth: 15 m. Length: 4 mm. 31 July 2005. natural channel. Photographer: Andre Couture

I have look in Debelius book on Nudi's and seem that it could be a Chromodoris verrieri but I have never seen the adult version in over 19 months of diving here.

Can someone confirm what kind it is exactly?

Dear Andre,
It's always difficult identifying juveniles, especially in a groupd like the chromodorids where their are a number of similarly coloured species to choose from. One real clue are the white edges to the rhinophores, which are found in only some of this colour group of chromodorids.

Chromodoris verrieri and Noumea subnivalis are two possibilities, and another is Chromodoris albonares which is characterised by having proportionally large rhinophores. Your animal has large rhinophores, but unfortunately proportionally large rhinophores are characteristic of all juvenile chromodorids so its not much of a clue in this case. As a guess I think Chromodoris verrieri is as good as any other.
Best wishes,
Bill Rudman
