Technical description: Consult Doromasia picta Chun, C, 

 Senckenb. Naturf. Gesellsch., Abh., 1892-95, p. 91, pi. 8, figs. 3-5, 

 pi. 9, figs. 5-10, pi. 10, figs. 1-9. 



The complete specimens in the "Alva" series conform in every- 

 way with Dr. Chun's excellent description and exquisite illustra- 

 tion of this siphonophore. Variation in the extent of dentition 

 occurs along the lateral ridges of the prismatic nectophore, in 

 the present series of specimens. One of the largest specimens, 

 with the nectophore 24 millimeters long, has these ridges serrate 

 throughout their length ; another nectophore, 16 millimeters long, 

 has some of the ridges entirely serrate, others smooth. Very small 

 nectophores, from 10, 12 to 14 millimeters long, do not have any 

 more serration than is shown in plate 8, figure 3, of Chun's type 

 illustration.

 Islands ; the depository was not given.

 Atlantic from the Canary Islands to the West Indies and also 

 from the Indian Ocean (Huxley) , the Malaysian region (Lens and 

 Van Riemsdijk) and is abundant in the eastern tropical Pacific
