In the original locality the rock— our common limestone — was 

 evidently too hard for perforation, hence the burrow was built upon 

 it ; but in my latest find the shrimp (Axius plectorynchus, Strake) 

 has made a hole in the rock, a calciferous sandstone. This burrow 

 is lined with a tenacious brown mud, composed of excrementitious 

 matter ; and, in addition to the mud lining, there is always more or 

 less present an orange-coloured sponge which I have never found 

 elsewhere. Upon the mud or sponge, and adhering very closely, 

 are found the Ephippodonta. They quickly form a pit-like depression 

 by means of their foot, and appear almost covered by the mud. 

 I have also taken off the burrow, and only there, all the three 

 species of Mylitta known to us, viz., deshayestana, tasmanica, and 

 gemmata ; as likewise a species of Kellia. 



The burrows are found at all angles, but chiefly horizontal, they 

 are perfectly circular and vary in diameter from half an inch to an 

 inch and a half. It is rare to find more than one shrimp in a burrow. 

 During the winter months, say from about March to July, I have 

 found the burrows completely filled with minced seaweed, of such 

 kinds as clothe the rocks beneath which the shrimp lives. Is this 

 a provision for the stormy season ? Upon removing the chopped up 

 weed one occasionally finds immense numbers of minute Ephippodtmta 

 lining the burrows. 



[Mr. Matthews has sent over in illustration of his paper specimens 

 of Ephippodonta in spirit ; also specimens of the shrimp, burrow, 

 sponge, &c. All the above have been presented to the Natural 

 History Museum, South Kensington. It is hoped that a paper on 

 the anatomy of the genus may shortly be published. — E. R. Sykes.]
