Stachyodes allmani (Wright and ^tudev) = Calypterinus allmani, Wright and 

 Studer. Plate II. figs. 1, 5a, and 5/>. 



Two fragments, evidently portions of a larger colony. The larger (A), which 

 is branched, is 196 mm. in height; the smaller (B), which is unbranched, is 147 

 mm. in height. 



The larger specimen differs from the typical habit of the species, inasmuch as 

 the branches arise alternately on three sides of the axis. 



The axis has at its lower end a diameter of 1-5 mm. in A and 1 mm. in B. 

 It is very brittle, slightly more flexible towards the apices of the branches, and 

 consists of a horny matrix filled with calcareous particles. 



The coenenchyma is so thin that the iridescent axis shines through. 



The polyps are arranged in verticels of four, with a distance of 2 mm. between 

 the origins of the verticels. This arrangement gives the polyps a somewhat 

 bilateral appearance, although they arise from three sides only, leaving on one 

 side a bare strip which is formed into a canal by means of the large flat polyp 



spicules. 



The locality of this specimen confirms the suggestion made by Wright and 

 Studer that C. allmani is a deep-sea species. 



Locality : Laccadive Sea ; 703 fathoms. 



The collection includes a complete young colony belonging to this species. 

 It is unbranched with the exception of a small stump near the base, which is the 

 basal portion of a liranch or twig, and it reaches a height of 41 mm. 



The polyps are arranged in a bilateral manner, in verticels of 3-4, and the 

 apex of the polyp when at rest is directed downwards. 



The development of the covered channel-like groove on the free side of the 

 axis is well seen. As in the large specimens, the coenenchyma is thin and allows 

 the axis to shine through. The basal attachment consists of a flat spreading portion. 



Locality : Station 226 ; 8° 36' 15" N., 81° 20' 30" K ; 542 fathoms.
