referred to : it has 178 ventral shields and 34 subcaudals — 

 numbers nearly identical with those of the typical example. 

 For the second species I propose the name of 



Diemenia Schlegelii. 



This is a conspicuously shorter species, having only (148, 

 Schlegel,) 149 or 155 ventral shields, and (24, Schlegel,) 24 or 

 21 subcaudals. The shields of the head are very much the 

 same as in the other species. Temporals 2 + 2 + 3, the lower 

 of the first series being intercalated between the last two 

 labials, and not in contact with the postoculars. Scales in 

 fifteen rows. The lower parts are more or less dotted with 

 brown ; and the lateral bands of the head are indistinct, if 

 present. 



Of this species we have two examples from the island of 

 Misol. 



Cacophis modesta. PI. III. fig. C. 



Scales smooth, in seventeen t^eries. Head of moderate width 

 and length, not depressed. Rostral shield somewhat project- 

 ing (as in Liophis comrostris) , higher than broad. Anterior 

 frontals one third or one fourth the size of posterior. Vertical 

 five-sided, much longer than broad ; occipitals as long as ver- 

 tical and postfrontals together, rounded behind. Nasal simple, 

 pierced in the middle by the nostril, in contact with the single 

 prseocular. Two postoculars. Six upper labials, the sixth as 

 long as the two preceding together. Temporals 1 + 2 + 3, the 

 foremost in contact with the occipital, lower postocular, and 

 two posterior labials. Eye of moderate size, with round pupil. 

 Ventrals and subcaudals 154 + 48, 157 + 49, 165 + 42. Anal 

 bifid. Upper parts uniform greenish olive, the lower whitish. 

 In one specimen a darker collar, edged with yellowish in 

 front and behind, is distinctly visible ; this specimen has also 

 greyish spots on the abdomen. Anteocular generally yellow. 



This species has the appearance of a Diemem'a, from which 

 genus it differs by its pholidosis. We liave obtained three 

 examples from Western and North-western Australia ; the 

 lai-gest is 16 inches long, the tail being 3 inches. One was 

 obtained at Perth by Mr. Duboulay. 



Pseudonaja affinis. PI. IV. fig. C 



This snake is readily distinguished from P. nuchalis by a 

 greater number of scales, which are arranged in nineteen 

 series. The rostral shield is much produced backwards above, 

 but less so than in its congener. Vertical, two thirds as broad 

 as long. Nostril wide, the division of the nasal being indi-
