66 Annals of the South African Museum. 



plate are called Squilla lata, while fig. 8 is named Squilla 

 Ursa minor. The last appears to be Scyllarus arctus, and 

 the position of the eyes suggests that fig. 3 is intended to 

 represent Themis oriental-is. But as Jonston's work has been 

 ruled out of court among treatises not consistently binomial, 

 a discussion of his rude figures may be dispensed with. 



The South African specimen is in unmistakable agree- 

 ment with the illustrations by various authors cited in the 

 synonymy. Milne Edwards speaks of the ocular peduncles 

 in this genus as very long, no doubt meaning comparatively 

 rather than absolutely. They enable the small cornea to 

 project only very slightly beyond the lateral borders of the 

 carapace. The stomach in our specimen is protruded, as 

 happens sometimes with animals brought suddenly to the 

 surface from a considerable depth. The first and second 

 segments of the pleon have each a small medio-ventral 

 process, the second much the smaller. Length of the speci- 

 men along the middle line, from the base of the cavity of the 

 frontal process to the end of the telson 139 mm., breadth 

 across front just behind the eyes 81 mm. Herbst says that 

 the flesh of the animal is good eating, better than that of the 

 lobster, as Eumph had observed many years earlier, though 

 for actual comparison of flavours one would not expect 

 Astacus gammarus to have been common in Amboyna, and 

 Thenus oriental-is, which is rare even in the East, can seldom 

 have come to table in Germany.
