Dactylochalina cylindracea, v. Lendenfeld ('?). 



The specimen in question offers a strong resemblance 

 in its external characters to the above species, as figured 

 by von Lendenfeld (5, PI. II., fig. ]) in his Monograph 

 of the "Horny Sponges," PL II., fig. 1. The sponge 

 is digitate, and consists of a number of slender cylindrical 

 branches arising from a common trunk . The entire height 

 of the specimen is 14 cm., the diameter of the branches 3 

 to 4 mm. The oscula are very small, less than 1 mm. in 

 diameter, and not raised. Consistency elastic. Colour 

 (in spirit) brown. The fibres are stout and contain a 

 large amount of spongin. The primary fibres, 0'045 mm.
