fathoms. The new Trachyp. salaco was captured at both Stations in water of 22 m. and the 

 atlantic Trachyp. co7istr ictus is not known from more than 27 fathoms, while Trachyp. siniilis 

 was taken at i to 2, but also at 31 fathoms. 



Remarks. An examination of the single type specimen of Penaetis barbatiis de Haan 

 (Fauna Japonica, Crust, p. 192, Tab. XLVI, Fig. 3) from Japan, which s})ecimen, kindly sent 

 me by Ur. Horst of the Leyden Museum, is in a dry .state, proved this species to be identical 

 with Penaeopsis akayebi (Rathb.). In this specimen, which is about 65 mm. long, the rostrum is 

 6 -|- I -dentate and reaches a little beyond the 2"'^ antennular article, while the epigastric tooth 

 is situated at the anterior fourth of the carapace. The carina of the 3"' abdominal tergum 

 slio-htly widens towards the posterior end and is flattened, though not grooved. I observe at 

 either side of the carina of the 4* abdominal tergum, about 1,5 mm. distant from it, a longi- 

 tudinal subcarina; these two subcarinae slightly diverge backward and are a little farther distant 

 from the posterior than from the anterior margin of the somite. They are not mentioned in 

 my description of Pen. akayebi (I.e. 1907, p. 433), but perhaps these subcarinae are a product 

 of the desiccation. The carapace without the rostrum is 12 mm. long; the 6"^ abdominal somite, 

 measured along the upper margin, appears to be 10,5 mm. long, it is 5,3 mm. wide (or high) 

 anteriorly, 4,3 mm. posteriorly and 5,3 mm. in the middle. These numbers closely accord, as 

 regards their proportions, with those which I have indicated, in the quoted paper, for Pen. 

 akayebi (Rathb.). 



The i^' legs are bispinose, the 2"'^ unispinose, but the 3'''^ seem to be unarmed, though 

 DE Haan describes "pedes tres antici basi unispinosi". 



The stridulating organ fully agrees with that of Pen. akayebi (de Man, 1. c. p. 434, 

 PI. XXXllI, Fig. 54) and is composed of 18 — 20 transverse ridges. 



The specimen seems to be a male, but the petasma and the two last pairs of legs are lost.

Stat. 51. April 19. Madura-bay and other localities in the southern part of Molo-strait. 



From 54 — 90 m. Fine grey sand ; coarse sand with shells and stones, i young 



male and 2 young females. 

 Stat. 153. August 14. 0° 3'.8 N., 130° 24'. 3 E. Halmaheira Sea. 141 m. Fine and coarse sand 



with dead shells, i young male. ^ 



Stat. 162. August 18. Between Loslos and Broken-islands, west coast of Salawatti. 18 m. 



Coarse and fine sand with clay and shells, i young male. 

 Stat. 289. January 20. 9°o'.3 S., I26°24'.5E. Timor Sea. 112 m. Mud, sand and shells, i male 



of medium size. 



The two adult females of Trachyp. cnrvirostris (Stimps.) from the Inland Sea of Japan, 

 described by me in 1907 (Trans. Linn. Soc. London, Ser. 2. Zool. Vol. IX, p. 436, PI. XXXIII, 

 Fio-. 56 — 58) are lying before me. Stimpsgn's species seems to be indeed different from that 

 which was collected by the "Siboga" and which is perhaps identical with Pen. granulosus Hasw.
