sand. I female. 



These specimens that are all young and much injured, are probably to be regarded as 

 individual varieties of Sol. pectinata (Sp. Bate). In these specimens the prominent, posterior 

 margin of the subhepatic groove, i. e. the anterior part of the cervical groove, runs straight 

 downward and forward to just near the rounded, antero-inferior angle of the carapace, forming 

 here no obtuse, dentiform lobe, because the groove does not curve around it, before 

 reaching the edge of the carapace. In some specimens, as in the female from Stat. 294, the 

 carina of the 3'"'^ tergum is more prominent; in this female the telson is longer than in the 

 typical species, being as long as the inner uropod, but shorter than the outer. In this specimen 

 the antennular peduncles are missing, but in the larger female from Stat. 19, which for the 

 rest does not differ, the antennular peduncles reach nearly to the apex of the antennal scales, 

 while in Sol. pectinata they are much shorter. In this female from Stat. 19 the carapace, 

 rostrum excluded, is 9,75 mm. long, measured near the dorsal line, and the antennular flagella, 

 that resemble those of Sol. pectinata, are 22,5 mm. long, more than twice as long as the 

 carapace. In the other female from Stat. 19 the carapace is 6 mm. long without the rostrum, 

 and the antennular flagella measure 15,75 ^n™- 



In the young male from Stat. 64, that was taken together with a specimen of Sol. 

 pectinata.^, the carapace without the rostrum is 7 mm. long, the antennular flagella measure 

 9,5 mm. and the 3'^'' abdominal tergum is not carinate.

Stat. 302. February 2. 10° 27^9 S., 123° 28'. 7 E. Near Rotti Island. 216 m. Sand and coralsand. 



I adult female. 

 Stat. 306. February 8. 8°27'S., I22°54'.5E. Lobetobi Strait. 247 m. Sandy mud. 9 males, 



6 females. 

 Stat. 312. February 14. 8° 19' S., ii7°4i'E. Saleh-bay, north coast of Sumbawa. 274 m. Fine, 



sandy mud. 2 males, 2 females. 



In its outer appearance Sol. Melantho, of which the male attains a length of 100 mm., 

 the female one of 132 mm., much resembles a species from Japan, which, in 1884, was wrongly 

 referred by Carl Koelbel to Sol. distincta (de Haan). I am indebted for this knowledge to 

 Dr. HoRST of the Leyden Museum, who kindly compared for me the Siboga species and 

 Koelbel's description (in: Sitzungsber. K. Akad. Wiss. Wien. Bd. XC. 1884, p. 314, Taf. II, 

 Fig. I — 7) with the single type, a female, of Penaeus distinctus de Haan: I propose therefore 

 for Koelbel's species the name of Sol. Koelbeli.
