 Port Albert, oft' Lakes Entrace, etc., Warrnambool and Port 

 Fairy. 



Obs. — In this case also considerable lumping is necessary, 

 especially in view of what is now commonly accepted by many 

 as simple variation in very common species. The very large 

 foi'm of this species S. maxima is not by any means common, but 

 is usually obtained off Cape Schanck, or in the neighbourhood of 

 the Ninety-Mile Beach, Gippsland, and at first sight it would 

 certainly appear to be a good species, but many links seem to 

 undoubtedly connect it with S. dilatata. F. pastinaca, Reeve, 

 and F. tasmaniensis, Adams and Angas, are also forms insepar- 

 able from the above. Siphonalia oligostira, Tate, is a form which 

 can be obtained at Warrnambool and Port Fairy, as well as in 

 South Australia ; and is but a relatively non costate, fusiform 

 variety, and bears exactly the same relation to the ordinary type 

 of S. dilatata, Quoy and Gaimard, as the fusiform variety of 

 Fusus coronata, Lamarck, commonly referred to as F. fusiformis, 

 does to its ordinary coronate type. As we have already admitted 

 this variation in the case of the Fusus we cannot possibly neglect 

 it in this instance. Fusus adustus, Philippi, may also be a 

 synonym of this species.
