<p>The genus <em>Chondrilla</em> is reported from the Andaman group of Islands off Havelock Island for the first time, with two species, <em>C. grandistellata</em> and <em>C. australiensis</em> in this study.  This genus has previously been reported and represented by four species in Indian waters viz., <em>Chondrilla mixta, C. sacciformis, C. kilakaria </em>and<em> C. australiensis.</em> <em>C. australiensis</em> is light brown to reddish-brown in colour; encrusts primarily on live boulder corals; contains oxyasters measuring 14.8-(18.5)-22.2 µm and spherasters measuring 17.3-(26)-29.7 µm. <em>C. grandistellata</em> is tan or brown in colour with unevenly distributed white speckles; Contains large spherasters that measure 106.3-(143.3)-175.6 µm.  In this study it is suggested that <em>C. sacciformis</em> specimens reported previously from India may be <em>C. grandistellata</em>; this probable conspecificity is also discussed. </p><div> </div>
