NO. IO CRINOIDS OF HAMBURG MUSEUM — CLARK 25 



3. A T o Locality.- — Two typical specimens; one of then; has rather 

 long proximal pinnules, the other has them rather short. 



4. Hong Kong. — One specimen. 



5. Mortlock Island, Carolines. — Two specimens, each with thirty 

 arms 80 mm. long; there are 22 or 23 cirrus segments; P 2 is from 

 10 mm. to 12 mm. long with from twenty-six to thirty-seven segments, 

 rather slender; there is no apparent enlargement on the outer arms, 

 but the outer pinnules are much longer, reaching 18 mm. 



6. No Locality.- — One specimen ; P. on the outer arms is exception- 

 ally long. 



7. Isabcla, Basilan, Province of Mindanao; Dr. II. Hallier. — One 

 specimen; the dorsal pole of the centrodorsal is 3 mm. in diameter; 

 the centrodorsal is thin discoidal, bearing cirrus sockets in two ir- 

 regular marginal rows ; the cirri are XXIV, 26-29, 2^ mm. to 25 mm. 

 long; the pinnulation agrees with that of the type of cequipinna, and 

 this is in every way very similar to that specimen.

2. Port Denison, Queensland. — One specimen with about forty- 

 three arms about 85 mm. long and cirri XLII, 24-27, 17 mm. long ; P 2 

 is 18 mm. long, very slender, with thirty-three segments; on the 

 innermost side of the 1 1 Br series P 2 is nearly as large as on the outer 

 side, but elsewhere it is small; on some of the arms P a resembles P 2 ; 

 the proximal pinnules are less carinate than usual. 



3. Bozvcn, Queensland. — One specimen, smaller than the preceding. 



Family COLOBOMETRIDiE 

 PETASOMETRA, new genus 



This new genus is related to Deeametra and to Cyllonietra. The 

 arms are from ten to twenty or more in number, the IIBr series being 

 4(3 + 4), rarely 2. P„ is always absent. \\ is as long as, and similar 

 to, P 2 ; the following pinnules are shorter.
