alimentary tract is distinctly divided into stomach and intestine. 

 Just above the constriction which marks the commencement 

 of the peduncle is a ring of strongly developed foot glands, 

 probably accounting for the amount of material in the axis 

 of the colony. These glands are very marked, and together 

 with the constriction differentiate the species from all others 

 of the genus I am acquainted with. The species more nearly 

 resembles L. racemovata (Thorpe) than any other, the points 

 of agreement being the form of the colony, position of the eyes 

 and antennae — taking the ventral figure given by Thorpe — 

 differing in the form of the corona, the trophi, and most 

 markedly by possessing the constricted trunk and strong foot 

 glands, Surgeon Thorpe's figures showing no trace of these 

 features. 



Mr. W. Stickland has very kindly drawn on wood and 

 engraved the figures. 



The specific characters may be summed up as follows : — 

 Clusters elliptical, with well-developed axis ; gelatinous adhering 

 tubes. Corona circular, slightly wider than body. Dorsal gap 

 absent, or very minute. Antennas, two, minute, ventral, but 

 wide apart. Body constricted at commencement of peduncle. 

 Foot glands strongly developed. Dimensions : — Individuals, 

 length .65 mm., breadth .085mm.; corona, .1 mm. across; 

 trophi, .032 mm. across ; ova, .09 x .047 mm. Habitat — 

 Heidelberg, Victoria. 



A PEEP INTO THE ROCKY POOLS OF SORRENTO 

 AND QUEENSCLIFF. 



Part II. 

 By Henry Thos. Tisdall. 

 {Read before the Field Naturalists' Club of Victoria, \2th Jidy, 1897.) 

 The green seaweeds which I described in my last paper as being 

 the principal denizens of the first pool uncovered by the receding 

 tide are not so common in the half-tide pool. The lovely 

 Padinse, with their changeful hues of green, grey, and purple, 

 immediately catch the eye. They grow on the rocks on the sides 

 of the pool, and seem to have a gentle undulating movement, 

 even in the most placid water. 



If we lift up some of those great olive-green masses of seaweed 

 we shall find beneath them fronds of Ceramium. These are 

 thread-like, jointed, and constantly forking into branches, the tips 

 of the filaments curling towards each other in a curious manner. 

 Under a low power the filaments appear like net-work of pink and 

 white, while the joints are almost transparent. 



Some species of Ceramium are quite scarlet, and the fertile
