4. Polyodontes gracilis Pflugfelder (1932, pp. 288-290) from Su- 

 matra. Penicillate neuropodial setae were described but whether 

 or not parapodial branchiae are present was not stated. The para- 

 podia were said to be like those of P. tidemani Pflugfelder, which, 

 in turn, was referred to Eupolyodontes sumatranus Pflugfelder 

 (1932, p. 282). 



5. Eupompe grubei Kinberg (1910, p. 24) from Guajaquil, western 

 South America. 



6. Panthalis jogasimae Izuka (1912, pp. 68-71) from Japan. Monro 

 (1928a, p. 568) reported this from Gorgona Island. 



7. Polyodontes mortenseni Monro (1928a, pp. 569-572) from 

 Panama. 



8. Panthalis melanonotiis Grube (1876, p. 71) from the Philippine 

 Islands (see also P. bicolor Grube, above). 



9. Panthalis oerstedi Kinberg (1855, p. 387) from Sweden (see 

 Fauvel, 1923, p. 98, for synonymy). 



10. Panthalis pacifica Treadwell (1914, pp. 184-186) from southern 

 California. 



11. Panthalis pustulata Treadwell (1924, pp. 7-9) from the West 

 Indies. This includes Acoetes magnifica Treadwell (1929, pp. 1-4) 

 from the West Indies. 



The following species, that have been described as Panthalis, are 

 perhaps to be considered as follows: 



P. adumbrata Hoagland (1920, p. 606) from the Philippines (see 



Polyodontes, page 82). 

 P. helleri Holly (1934, pp. 148-149) from the Philippines, identical 



with P. admnbrata. 

 P. edriophthalma Potts (1910, pp. 345-346) from the Indian Ocean, a 



Eupanthalis (see Fauvel, 1932, pp. 41-42). 

 P. nigromaculata Grube (1878b, pp. 50-51) from the Philippines, a 



Eupanthalis (see Horst, 1917, pp. 134-135). 

 P. oculea Treadwell (1902, pp. 188-189) from Puerto Rico, a Polyo- 

 dontes (see Monro, 1928a, pp. 572-573). 

 P. panamensis Chamberlin (1919a, pp. 86-89) from Panama (see 



Polyodontes, page 82).

 Collections. — ?244-34, 492-36. Two anterior fragments. 

 An anterior fragment of about 23 segments (492-36), with elytra 

 more or less firmly attached, retains some pigment in the elytra. The
