THE BURROWING BARNACLES (CIRRIPEDIA: ACROTHORACICA ) 69 



a tergum of a small Balanus tintinnahulum, from Malembe, Cabinda, 

 Angola (about 5°20' S). In such a restrictive habitat it is not surprizing 

 that a very small animal develops (see above for the small sizes of the 

 Ghana material), and its estimated 0.83 mm greatest length might 

 reflect a young animal or one which could not develop any larger. 

 The opercular armament resembles that of a young specimen from 

 TJiais haemastoma from Cadiz, Spain (the type-locality) (fig. 13o). 

 The latter specimen is about 1.6 mm long (estimated from a flattened 

 state), and believed to be somewhat older than Stubbings' specimen. 

 The similarity in teeth and the apical opercular "mound" is striking. 



I have examined Stubbings' specimen of K. inermis, through the 

 courtesy of the Musee Royal de TAfrique Centrale, Tervuren, 

 Belgium. No apparent differences from the description of K. hamata 

 were noted, although I did not corrode the specimen to check for a 

 lateral bar. No lateral bar was seen. 



The presence of a weak granular lateral bar in my specimen is 

 probably due to its greater maturity, as of course younger ones would 

 not have such obvious structures. I do not consider the variation in 

 the mouthparts significant. The ventral prominences posterior to the 

 mouth region are found in K. hamata, also. 



The distribution of K. hamata, from much of the west coast of 

 Africa, Europe, and the Mediterranean, adds strength to the argument 

 that K. inermis is a young K. hamata. 



Kochlorine anchorella, new species 



FlQUHE 14 



Diagnosis: Kochlorine with pointed mantle aperture armed with 

 three to four pairs of large, anchor-shaped teeth, plus numerous small 

 bifid teeth and many hairs. 



Etymology: Named for the anchor-shaped teeth on the operculum. 



Distribution: Four specimens from Chama lazarus L. from Heron 

 Island or northern Queensland, Australia, in the coUection of the 

 Victoria National Museum. Holotype VNM. Paratypes SFSC, 

 USNM, size 2.35 X 1.38 mm in length and width, with aperture 

 0.85 mm long. Three fragments from Bursa ruheta gigantea Smith 

 from Woolgoolga, N.S.W., Australia, from the AustraHan Museum 

 collection. The size of the figured specimen (cleaned in KOH) is 

 3.0 X 1.6 mm. The holotype and two paratypes average 2.50 X 1.40 

 mm, with an aperture of 0.88 mm. 



It has been identified in an unidentifiable piece of coral beheved to 

 be from northeast Australia, but with no locahty data. 



Type-material: Holotype: Vict. J-190. Paratypes: SFSC, USNM.
