BATHYPELAGIC SQUID BATHYTEUTHIS 57 



are very slightly irregular with minute denticles. The first lateral 

 tooth has a straiglit, blunt cusp about as long as the rhachidian cusp; 

 the concave lateral border has a few small, irregular denticles. The 

 second lateral tooth has a long, straight pointed cusp. The third lateral 

 has a very long, thin, sc>i: he -shaped cusp. The marginal platelets are 

 irregularly shaped oblong structures. 



The rhachis of the gladius is very long and slender: it makes up 

 60% of the total length of the gladius (pi. 12b). No median 

 ridge occurs along the gladius, but the lateral edges are rolled under to 

 form strong rodlike supports to the rhachis. These rods extend 

 posteriorly, decreasing in diameter, nearly to the tip of the gladius. 

 Tlie rhachis is U-shaped in cross section. The anterior tip of the rhachis 

 is very thin and flaplike. The vane is very broad, thin, membranous 

 and paddle-shaped. The rounded posterior border of the vane curves 

 ventrally and forms a shallow cuplike terminus. The gladius lacks a 

 conns. 



ISIost of the pigmentation is bleached out of the holotype, but the 

 smaller specimens exhibit the maroon coloration typical of 

 Bathyteuthis. 



The holotype is a mature male with fully developed sperma- 

 tophores in Needham's sac. A hectocotylus is lacking. Spermatophores 

 are about 8 mm in total length; the sperm mass occupies about 72% 

 of the total length, the cement body about 8% and the ejaculatory 

 apparatus about 20% (pi. 12e, f). The cement body is an elongate, 

 vase-shaped structure with a flaring lip or collar where it joins with 

 the narrow base of the short, bell-shaped end of the spiral filament. 

 About one-third to one-fourth of the spemn mass is slightly pigmented. 



The gills are long and broad ; counts and measurements were made 

 on the gills of six specimens ranging from 16-49 mm ML. Gill fila- 

 ments number from 19-21. The index of gill length to mantle length 

 ranges from 43 to H-S (mean 48.6). that of gill width to mantle length 

 from 7.5 to 15.7 (12.5), and that of gill width to gill length from 17 

 to 30 (25.5).
