NOTES ON SEA SNAKES FROM MADltAS. 



605 



by tlio number ot the subcaudal shields, and this enabled me to clear up a 

 point that I had previously never been able to elucidate. If one is justified 

 in assuming that the same habit hoUls good for all viviparous snakes, one 

 may infer that the male embrj'os of H. fayciatiis above referred to had 

 retracted the claspers, and were very near their nativity. 



In both adults the posterior sublingual shields were completely separated. 



UYjmOVUIS ORNATUS (Gray). 



A typical young specimen, apparently this year's progeny. The tem- 

 porals are Ixl. The supralabials 7, the 2nd not in contact with the 

 praefrontal. The costals juxtaposed throughout. 



There are 4.j black crossbars on the body, o on the tail. On the body 

 they are much broader than the intervals. A subcostal row of faint darkish 

 sports alternate with the crossbars. 



HYDROPBIS CYANOCINCTUS (Daudiu). 



The claspers are not bifid.
