REPORT ON THE A NOMURA. 119 



armed with somewhat larger spines than is usual in species of Galathea. The carapace 

 measures 10*5 mm. in length, and the rostrum 4 mm.; Stimpson's type-specimen came 

 from Ousima Island and was of smaller size.

Habitat. — Station 209, ofl" Zebu, Philippines, January 19, 1875; depth, 95 to 100 

 fathoms ; bottom, blue mud. A male without chelipedes or limbs. 



As in the case of the two preceding species this identification must be held to be 

 somewhat doubtful. The rostrum is broad, triangular, and deflexed, with five or six 

 minute teeth on each lateral border, and the upper surface pubescent. The striae on 

 the carapace are numerous and strongly ciliated ; the gastric region is unarmed. The 

 merus of the external maxillipedes is slightly shorter than the ischium, its inner margin 

 is bispinose, and the outer surface is obscurely squamose ; a few minute dentations are 

 present on the outer margin of both merus and carpus. The sculpture of the abdominal 

 segments is more strongly marked than usual. I believe that Galathea defiexifrons, 

 Haswell, will prove to be identical with this species and not with Galathea elegans, 

 ^\Tiite, as suggested by Miers, for Stimpson expressly states that his types are allied to 

 the latter. The carapace of the Challenger specimen measures 7 mm. in length.

Habitat. — Station VIIp, oflf Tenerife, Canaries, February 10, 1873; depth, 75 

 fathoms ; bottom, volcanic sand. Two specimens, male and female, the latter with ova. 



The rostrum is armed with four spines on each side which increase in size from 

 behind forwards, and its upper surface is pubescent. The first striated ridge on the 

 gastric area, situated at the base of the rostrum, bears from two to six spinules, but in 

 some cases they are obsolete ; the number of spines on the lateral border of the carapace 

 varies considerably and one or two spinules may be present on the hepatic area. The 

 ischium of the external maxillipedes bears an elevated longitudinal line near the middle of 

 its outer surface, and the lateral margins are prolonged distally into two acute spines, of 

 which the external is more prominent ; the merus is shorter than the ischium, and an 

 acute spine always exists near the middle of its inner margin, the two lateral margins 

 are usually prolonged distally into minute spinules, and one or two spinules are frequently
