thth. On shells and stones beyond low water mark, and 

 on shells from deep water; common; at Talland sand-bay. 



There are two varieties of this species, one branched and 

 the other not. The branched variety gives off its branches 

 in a very irregular manner, and generally at an obtuse angle 

 with the trunk. This is however liable to considerable 

 variation and irregularity. The unbranched variety is gene- 

 rally found in clusters, interwoven at the base, and filiform. 

 This species is distinguished from the last, in dried specimens, 

 by the tubes being ringed at regular intervals, presenting the 

 appearance of the windpipe of a bird ; from which it derives 

 its name larynx. In a recent state, the rings are visible by 

 transmitted light. The polypes are naked, with two circles 

 of tentacula. The head is licjlit red, the tentacula are white, 

 or white fringed with red. The reproductive gemmules rise 

 from the base of the tentacula. 



* * Tubes branched. 

 T. RAIMOSA. Tube single and regularly branched ; alter- 

 nate and ringed ; the polypes with only a single row of 

 tentacula.

IJah. From deep water off the Dead man on the Pinna

This Species may be distinguished from branched varieties 

 of the preceding by the regularity with which the branches 

 arise, in an alternate manner. It appears to be confounded 

 witli several species, especially with the branched variety 

 of T. Larynx and the following, T. Ramca. In comparing 

 the two together there will be but little chance of confusion ; 

 but otherwise, it may be difficult to distinguish between them.
