The insertion of the lateral ten- tacles appears to be subterminal as in Halosydna, but of this I am not sure. The median tentacle is about of the same length as the long and rather slender palps, and it is longer than the lateral tentacles. The tentacular cirri are rather longer than the tentacles and there is a long ventral cirrus on the first foot. The elytrophore of the first foot is a cylindrical structure about half the length of the foot; the remaining elytrophores are conspicuous but not unusually prominent.
