162. Thyrsoidea miliarts. 

 Thyrsoidea miliaris, Kaup. 



Head short and blunt, and the front nostril- tube unusually 

 short. Jaws short, the length of tlie gape being contained once 

 and a half in the length of the space between the tip of the snout 

 and the gill-opening. 



This species resembles meleagriH (165), but the yellowish points, 

 like pins' heads, are smaller and more regular; the head also is 

 blunter, and the jaws are not so widely cleft. It likewise resembles 

 AtKjustl (158), but the dots are placed much closer in miliaris, and 

 the head of Augiisti is much more elongated. A large specimen 

 exists in the Paris collection, but it is not known wdience it came. 

 Another, sent by M. Acliard from Martinique, exhibits arabesque 

 figures towards the end of the tail, arising from the dots running 

 into each other. The inner part of the mouth is spotted. 



The following are the dimensions of the biggest specimen. To 

 the corner of the mouth, 125 in. To the gill-opening, 3 14 in. 

 To the anus, 1140 in. The length of the tail, 1258 in. Total 

 length, 23-98 in. The specimen from Martinique is 18-85 in.
