I follow their example, in order to avoid confusion, which will doubtless result by using the 

 same name for different but nearly allied animals. 



2. Glyphis Sicboldii Reeve. 



Reeve. Conch. Ie. Vol. VI, Fissurella, fig. 102. 



PlLSBRV. Man. of Conch. Vol. XII, p. 204, PI. 38, fig. 58, 59. 



Stat. 240. Banda. 9 — 45 M. Lithothamnion-bottom. 1 Spec. 



Stat. 282. Between Nusa Besi and N.E. point of Timor. 27 — 54 M. Sand, coral and Lithotham- 

 nion. 4 Spec. 



Three of the specimens from Stat. 282 are very small and not characteristic, however 

 they agree sufficiently with the upper part of larger specimens. 



3. Glyphis Reevei nom. nov. 



= Fissurella excelsa Reeve. Conch. Ie. Vol. VI, fig. 113 (not Adams and Reeve). 



Stat. 51. Madura-bay and other localities in the southern part of Molo-strait. 69 — 91 M. 



Fine grey sand; coarse sand with shells and stones. 1 Spec. 



Stat. 60. Haingsisi. 36 M. 1 Spec. 



Stat. 71. Makassar and surroundings. Up to 32 M. Mud, sand with mud. 1 Spec. 



Stat. 116. West of Kwandang-bay-entrance. 72 M. Fine sand with mud. 1 Spec. 



Stat. 162. West-coast of Salawatti. 18 M. Coarse and fine sand with clay and shells. 1 Spec. 



Stat. 164. i°42'.5 S., i30°47'.5 E. 32 M. Sand, small stones and shells. 1 Spec. 



In the year 1848, Adams and Reeve (Zool. "Samarang", Moll. p. 70, PI. 11, fig. 5) have 

 described a different species under the name excelsa. The plate of Reeve's Conch. Ie. being of 

 1850, his species must have a new name. 



As the figures of Reeve and pilsbry (Man. of Conch. Vol. XII, pi. 39, fig. 96) represent 

 the species only from the back-view and they give no measurements, I give those of the largest 

 specimen, from Stat. 7 1 . 



Long. 14 1 /.,. lat. 9, alt. 9 Mill. 



Pilsbry (1. c. p. 209) suggests that Fissurella excelsa Reeve should be a synonym of 

 Glyphis alta C. B. Adams from Panama, though Reeve says: "Eastern seas", but though the 

 figure of Pilsbry, agrees in many respects with the Siboga specimens, I think it is not probable 

 that they belong to the same species, since the latter specimens justify Reeve's locality. 



4. Glypliis licaouica Reeve. 



Reeve. Conch. Ie. Vol. VI, Fissurella, fig. 107. 



Pilsbry. Man. of Conch. Vol. XII, p. 225, PI. 36, fig. 20. 



Stat. 98. 6°9'N., i20°2i'E. 350 M. Sand. 2 Spec. 



Stat. 144. North of Damar-island. 45 M. Coral bottom and Lithothamnion. 1 Spec. 



Stat. 258. Tual-anchorage, Kei-islands. 22 M. Lithothamnion, sand and coral. 1 Spec. 



The shells from Stat. 98 are dead; it is not without doubt that I have identified them, but 

 they agree rather well with those from the other localities, and may have lived at similar depth.
