Remarks. Voris and Jeffries collected the only specimen of H. schistosus from Singapore from a kelong at LCK on 28 July 1981 ( Fig. 22F View FIGURE 22 ). This specimen was deposited at the Raffles Museum and is catalogued under ZRC.2.2047. Cantor (1847c) was the first to report H. schistosus from Singapore, and in his account of the species he stated that it was the most abundant sea snake in Singapore, as did Horwood (1968). Sharma (1973) and Gremli (1988c) also both declared that H. schistosus was common in Singapore, and Shelford (1916) recounted H. schistosus as one of the most common sea snakes in the South China Sea between Singapore and Sarawak, Malaysia, and Borneo. However, neither of these authors provided any evidence. Thus, it appears that H. schistosus may be common in the waters surrounding Singapore, but the Voris and Jeffries specimen is the only record from Singapore.
