DistributionAustralia (Northern Territory)

Type locality: Yirrikala Mission Station, near Caledon Bay, Arnhem Land, Northern Territory.  
TypesHolotype: AMS (AM) R12381, collected by Rev W.S. Chaseling. 
DiagnosisDefinition. Nasal cleft in contact with the first labial. Scales in 24 rows round the centre of the body. Head and snout rounded. Nostrils inferior, nasal not completely divided, the nasal cleft terminating a fraction in front of the nostril, and not visible from above. Rostral from above, rounded, as broad as long, more than half the width of the head, and not extending back to the level of the eyes; the portion visible from below is broader than long. Preoculars narrower than the nasals, the latter forming a narrow suture, separating the prefrontal from the rostral. Frontal smaller than the prefrontal. Parietals and inter-parietals about equal in size, but not much larger than the nuchals. Total length 182 mm. Width about 3 mm (Kinghorn 1942: 118). 
CommentOriginal description based on a single specimen. 
EtymologyNamed after Yirrkala Mission – the original author spelt the locality erroneously as Yirrkala Mission in the paper; note that the Code considers the name, as originally spelt as valid (unless the criteria of Article 32.5 apply, which requires evidence in the original publication itself of an inadvertent error).
