Gray, Try on, and Gould, the following six genera are established, 
chiefly based on the form of their siphonal palettes : — 
1. Teredo (L.). Siphonal palettes simple, oblong, transverse, entire, rarely 
serrated or toothed. 
2. Nausitora (P. Wright). Siphonal palettes on the outer surface convex, 
covered with thick scale-like stiise ; inner flat or slightly concave. — N. 
dunlopei (P. Wright), described in the preceding volume of the same 
journal, freshwater, India, and a new species, N. saulii, p. 667, pi. 66. figs. 9- 
16 ; valves with well-developed auricles, from Port Phillip, Australia. 
3. Kuphm (Guettard). Siphonal palettes with apex dilated, transverse, 
spathulate, with a central midrib and an elongated, slender, cylindrical base. 
Siphons free throughout the greater part of their length.-^ A", arenarius (L.) 
and K. ? mannii, sp. n., p. 666, pi. 65. figs. 1-8, Singapore, in timber, whilst 
K. arenarius lives in sand or soft mud. 
4. Calohates (Govldi). Siphonal palettes large, long, stilt-shaped ; siphons 
adherent, only becoming free at their tips. — C. thoracites (Gould, Proc. Post. 
Soc. 1866) = Teredo furcelloides (Gray, Proc. Zool. Soc. 1861), described p. 664, 
pi. 64. figs. 6-12, from Tavoy and also from Singapore, where it lives in the 
timber of the same jetty as Kuplms mannii. — C, australis j sp. n., Wright, 
p. 664, pi. 64. figs. 1-6, Freemantle, Western Australia. 
6. Xylotrya (Leach). Siphonal palettes elongate, penniform, horny, lateral 
edges with short filaments, spongy texture. — X, hipinnata (Turt.), X. Jim-* 
hriata (Jeffr.) &c. 
6. Uperotus (Guettard). Siphonal palettes spoon-shaped, depressed; area 
elegantly ribbed, ribs forming teeth on the upper margin. — XJ, clava (Gmel.).

The specimens dissected belong to F. grandis, from 
New Caledonia, and prove the genus to be distinct from Gas^ 
trochcBnaj although nearly allied to it. Type F. mumia (Spengl.).
