SUPPLEMENTARY NOTES ON HALOBATES, &c. 

 BY J. J. WALKER, E.N., P.L.S. 



I am much indebted to Dr. E. Bergroth, of Tammerfors, Finland, 

 and to Mr. Gr. H. Carpenter, o£ the Science and Art Museum, Dublin, 

 for kindly calling my attention to three recently described species of 

 Salohates, which I had omitted to notice in my paper on this genus 

 {ante pp. 227 et seq.). These are — 



l.—H.splendens,'Wii\s^C'z\], "Wien,Ent. Zeit.," 1886, p. 178, fig. 1, 

 and " Zoologischer Anzeiger," 1887, pp. 336 — 9. Habitat, Eastern 

 Pacific Ocean, south of the Galapagos Islands. 



2. —R. incanus, With, " Wien, Ent. Zeit.," 1886, p. 179, fig. 2, and 

 " Zool. Anzeiger," J 887, pp. 336—9. Habitat, Indian Ocean (Arabian 

 Sea, N. E. and S. E. of the Island of Sokotra). 



3. — S. inermis, Dahl, " Ergebnisse der Plankton-Expedition der 

 Humboldt-Stiftung," 1893, vol. ii, G, a, of. (Die Halohatiden der 

 Plankton-Expedition, von Dr. E. Dahl, 1893, p. 6, figs. 7 and 8). 

 Habitat, Tropical Atlantic Ocean, lat. 10° N., long. 22° W. 



The first two were obtained during the scientific voyage round 

 the world of the Italian corvette " Yettor Pisani," and the third was 

 found by the recent " Plankton-Expedition der Hun^iboldt-Stiftung," 

 for the investigation of the surface-fauna of the Atlantic Ocean. 



In "Zool. Anzeiger," vol. x, p. 338 (1887), Dr. Witlaczil records 

 the following very interesting observation respecting the oviposition 

 of Halohates : —"■ By the ' Pisani' a bird's feather was picked up at 

 sea quite covered with eggs, which it was determined belonged to 

 ILalobates. Unfortunately, the same were in the last stage of de- 

 velopment, so that they were of no use to me for the embryology of 

 the animals." 



Fr. Meinert (Slaegten Metrocoris, Mayr, og dens " forma prsema- 

 tura" IIalohatodes,'Wh.\te, in " Entomologiske Meddelelser," Kjoben- 

 havn, Bd. i, p. 140, 1887) discusses the relations of the two genera, and 

 regards Salohatodes as an immature form of 3Ietrocoris.
