Dongonab, Red Sea. 9.1916. 



Miiiiy of the tubes were empty, and the forms were youDf^. 



In the Red Sea Filot/rana [)rodiices ova in thi; cohlcht 

 month of the year. lu the same re^^ion Dr. Crosshind * 

 found that Melenyrina vu/ffaris sheds ova in the winter, 

 whilst 3/. margaritifera bieeds only in the summer. The 

 same eareful observer remarks tliut he has not yet seen 

 Filograiia amonjifst coral, but it is common on buoys, on the 

 bottoms of boats which have been standing in the liarbour, 

 on piles in sheltered water, and in sponges. All its habitats 

 in shallow water are sheltered, and the fragility of the 

 calcareous tubes probably render this necessary. 



Madras Harbour, India f. 



Tubes of the same form were dredged by the late Dr. John 

 Anderson east of \'erriblcs, India, in l.'j fathoms. 



The branchicc of those from Madras Harbour show slight 

 enlargements at the tips of the filaments. Tiiough the 

 })rtparation8 were not very favourable, yet in an example one 

 of the tips exceeded the others in size, but had the same 

 structure. As a rule, the tips are probe-pointed, though in 

 some the terminal cushions are larger and more boldly 

 glandular. From seven to eight pairs of bristles occur in 

 the anterior region. So far as could be observed, the 

 structure of the collar-bristles is typical. 



Sydney Harbuur, Australia. 4.1916 J. 



The specimens are characterized by the blackish colour § 

 of the branchiae — especially their distal ends, which thus 

 boldly contrast with the white tubes, and the anterior region 

 of. the body in some is al>o of a dark hue. The branchiie 

 appeared to be comparatively thick and stumpy, the piunje 

 in some and the terminal process of the filaneut devoid of 

 ( nlargement, though it was stout. All had two eyes. The 

 numbir of the bristle-bundles of the anterior region was 

 usually nine, young forms had eight. There were no 

 opercula. Tlie collar-bris>tles agree with the type found at 

 St. Andrews.
