Specimens of different sizes vary somewhat in appearance. In 

 small specimens about 30 mm. long, the tips of the ventrals reach 

 slightly beyond the anus. In large specimens the anus is far behind 

 the tips of the ventrals. A specimen from Barrington Island, 520 

 mm. in length, has the anus 26 mm. back of the ventrals, while one 

 from Clarion Island 650 mm. long has a space of 83 mm. between 

 the anus and the tips of the ventrals. In some the maxillary reaches 

 considerably beyond the eye, in others it ends slightly in front of the 

 eye. The spots vary from simple circular black areas to irregular 

 dark blotches surrounded by broad white marginal fields each having 

 the same outline as the dark spot it encloses.
