Sorry for the delay. We thought we would have some additional info, but didn't get to it.

We have not seen an ovalis-like animal with the underlying color as found on the Samoan specimen. The orange spotting is close to that we find on the Guam animals and the gray would be the purple. The purple can be quite variable, some juvenile forms being mostly purple. Conclusion: probably H. ovalis (id warranted for 72 hours). As with many of the haminoeid forms, it is best to take a look at the animal.

I have attached a scan of the H. ovalis plate (Pease, 1868; Plate 7, fig.
2). I believe the drawing was done by Andrew Garrett. The original color description was: "Animal pale watery green, closely dotted with orange and purple. The portion seen through the shell is spotted obscurely with cream yellow, their margins powdered with white. Foot cream white, remotely dotted with pale orange. ..." (Pease, 1868:72)

Dear Clay & Patty Jo,
Thanks for the input. Pease make no mention of the black rings which are in the panting but not in his description. Perhaps they were just Garrett's way of showing the white ring around each orange spot.
Best wishes,
