Two spermatophores of Tylototriton {Echinotriton) andersoni deposited on a pebble and a shelter slate. Scale indicates 1 mm. Okinawajima that were smaller sibs of the female mentioned above. The male soon reacted to one of them and resumed the same behavior as described above. He pressed his cloaca to a shelter slate and left a clear mucous string on it. When the forelimb of the female became tangled in the mucus, she vigorously tried to remove it by rubbing her hand in the substrate sand and tried to escape from the male. Notwithstanding her action, the male persistently tried to move around the female drugging mucous strings from his cloaca. We failed to continue observation, but, ten min- utes later, we found two spermatophores, one on a pebble and another on the slate. They were connected by mucous strings and thus seemed to have been deposited one after the other (Fig. 2). Spermatophore morphology On 10 December 1981, we found two spermatophores attached to the surface of a slate shelter in a cage containing the male and the female from Amamioshima. Both sper- matophores were nearly conical in shape (Fig. 2), transparent like crystal, and partially spotted with white. Their material was hard but somewhat jelly-like. On 23 January 1982, the male from Amami- oshima again deposited a spermatophore on a slate. It was x mm in base diameter and mm in height. As in the previous case, the spermatophore was hard, jelly-like, and trans- parent with white portions on top and inside. Sperm morphology When one female from Tokunoshima laid eggs on 9 May 1973, we took them out of the soil and washed them in a small amount of water. We observed the water thus obtained under a light microscope, but could not find any sperms. 42 ' X
