An imperfect body with a complete skull of <I>Crocidura dsinezumi orii</I> Kuroda 1924, was found in a stomach of <I>Trimeresurus okinavensis</I>, which was colleced in July, 1960 by Mr. T. Morita and Dr. K. Koba at Yuwandake, Amami-Oshima, Japan. It is the second and unique specimen of <I>orii</I>, because this form has only been known by a type, a skin and an imperfect skull, collected in 1922 and destroyed by fire in 1945. The second specimen, adult male, is easily distinguished from <I>russula, sodyi, tanakae, thornasi, dsinezumi, umbrina, chisai, shantungensis, watasei</I> and <I>tadae</I> by relatively longer fur of the back (6.0-6.5 mm against 2.5×5.0 mm), decidedly larger claws of manus (2.7 mm against 1.1-1.8 mm), much shorter braincase (nearly circular against oblong), and posteriorly located posterior border of anteorbital foramen and anterior extremity of orbit. Therefore, this form may not be a subspecies of <I>dsinezumi</I> but a distinct species, <I>Crocidura orii</I>, peculiar to the small island.
