their becomiug shrivelled and dry before immersion in alcohol, the pres- 

 ent individual having been placed in spirits when alive. 



On the, under side of the head the skin (in a preserved specimen) lies 

 in irregular folds, which conform generally to the outline of the lower 

 jaw, the outer folds reaching the gill-opening. Between the lower lip 

 and these folds there is a series of papillae, which has its origin a short 

 distance behind the corner of the mouth, the series being slightly sepa- 

 rated close behind the symphysis of lower jaw by two small, rounded 

 flaps. The papilltTe number about fourteen on either side of the flaps. 

 On the superior surface of the snout, exterffling posteriorly half as far 

 as the termination of the maxillary, the skin is finely wrinkled, and 

 there is on either side a conspicuous flap, which seems to conceal a 

 nostril. 



The skin on the top of the head posterior to the wrinkled snout is 

 smooth and adherent to the muscles. Cheeks tumid. 



This species has the habit of burrowing into the sand on the removal 

 of the stone covering it, and in one instance a lively individual buried 

 itself in the sand a second time. It is of a clear pink color, shading 

 into yellow on the tail, and has a semi-transparent api)earance in life.
