NO. 2135. NEW PHILIPPINE CHAB.^l—RATHJBVN. 553 



Measurem-ents. — Length of carapace on median line, 41.2; length of 

 rostral horn, 13.1 ; width of carapace without spines, 31.6. 



A Maja with three long median spines, two gastric and one cardiac, 

 one dorsal branchial spine, four long marginal spines behind the 

 orbit, one of which is hepatic, two small spines on posterior margin 

 near the middle, a long curved spine at posterior end of preorbital 

 hood, followed by a short spine and then by a long postocular spine, 

 rostral horns about two-sevenths as long as remainder of carapace 

 and strongly divergent. Carapace covered with coarse granules 

 bearing setoe. Basal antennal segment armed with two spines at the 

 anterior angles, which are in line with the median deflexed spine of 

 the front. 



Chelipeds slender, smooth, sliorter than the next leg in the female- 

 Ambulatory legs smooth and hairy. 



Relationship. — Strongly resembles M. •m-/era^^ Walker,^ from Singa- 

 pore. Differs in having an additional gastric spine and in lacking 

 the secondary spine on the hepatic region. 



MAJA LINAPACANENSIS, new species. 



Type-locality. — Linapacan Strait: Observatory Island (N.), S. 

 55° W., 10.7 miles; lat. 11° 37' 15" N.; long. 119° 48' 45" E.; 46 

 fathoms; S. M.; Dec. 18, 1908; station 5335, Albatross.- 



Holoty])e.— Carapace only. Cat. No. 48225, U.S.N.M. 



Measure nwnts. — The figures are estimated, as the carapace is 

 broken posteriorly. Length of carapace on median line, 30; width 

 without spine, 27. 



A narrow, pyriform Maja with two median spines (one gastric, 

 one cardiac), a dorsal branchial spine in line with the cardiac spine, 

 two slightly divergent rostral horns (incomplete), three broad, flat 

 spines above orbit, one of which is attached to the narrow, preorbital 

 hood, postocular spine longest, intermediate spine well separated 

 fi'om the other tvs^ o ; about seven small, irregular lateral spines, of 

 whicli two are hepatic ; the anterior of these is the largest and forms 

 a right-angled sinus v/ith the postocular tooth. Surface covered with 

 irregular, punctate granules or tubercles. Vertical projection of 

 front triangular, tipped with a truncate spine. Basal segment of an- 

 tenna armed with three long blunt spines (two at anterior angles and 

 one at middle of inner margin) and four shorter spines or teeth (one 

 on anterior margin, three on inner margin) ; a granulated tubercle 

 on posterior edge of antennular cavities ; lower edge of orbit tubercu- 

 late. 



Relationship. — This appears to be much like ParaTnithrax {Lepto- 

 ■mithrax) conipressipes Miers,- from Canton, described from a larger
