Mus., xxiv, 898, 1902. This species is closely allied to S. tnoseri and S. maxilHpes, but is dis- tinguished by the short fingers of the first chelipeds, which are not more than a third as long as the palm. There are two specimens in the collection. The rostrum is distinctly shorter than the carapace, and, in the one specimen in which it is perfect, is armed with 6 teeth above (one on the carapace) and 3 below. No pterygostomia
