The alternative before us seems to be either to throw ligatus 
and torresianus together as one species, viz., ligatus, or to make 
the intermediate form a new species. 
Distira nasalis n.s. 
Rostral as long as broad ; nasal about five times as long 
as the inner prefrontal suture, shorter than frontal, its inferoposterior 
angle divided off by a groove from the nostril to the prefrontal 
and another to the second labial ; frontal much longer than broad, 
longer than its distance from the rostral, shorter than the parietals ; 
one pre- and two postoculars ; anterior temporal large, descending 
to the mouth ; six upper labials, third and fourth entering the orbit ; 
two pairs of chin shields, the anterior much the longer, in touch 
with three lower labials. Scale rows, 33 on neck ; 37 on body ; 
ventrals distinct, smooth. Whitish, with broad black bands 
across the dorsum and tail, and intermediate bands of spots 
more or less confluent ; sides and belly with dark spots ; tail 
beneath with bars alternating with its dorsal bands. One 
example in al., Queensland coast. 
Platurus frontalis n.s. 
A species with keeled ventrals and an azygous head-shield, 
but distinguished from P. schistorynchus by an entire rostral 
and shield-like temporals ; from P. muelleri by the azygous shield 
aforesaid, an elogate frontal and different lepidosis. 
Rostral, deeper than broad, entire, separating the nasals ; 
an azygous shield between the prefrontals ; frontal longer than 
parietals, its posterior angle acute ; seven upper labials, the third 
and fourth entering the orbit ; one pre- and two postoculars ; 
one anterior and two posterior temporals ; scale rows 21 round the 
body ; ventrals, 198, the last 30 keeled, except the divided penul- 
timate and preanal ; subcaudals 31. Head pale yellow, with 
black markings as in the other species ; dorsum with 34 black 
cross bands narrower than the spaces between them ; under surface 
nearly white. One example in al. Hab. New Guinea. 
VxVNAPINA n.g. 
Maxillary extending as far forwards as the palatine ; on it 
anteriorly a deeply-grooved fang, the groove folded over 
at the base, after a short diastema four or five small ungrooved 
teeth ; anterior mandibular teeth enlarged, fang like ; posterior 
minute, all ungrooved. Habit elongate cylindrical, tail short 
and thick ; eye very small ; pupil round ; nasal divided ; no 
loreal ; scales smooth in 17 rows ; ventrals rounded ; subcaudals 
paired.
