Description 



PI Ri with 2 inner setae; P2 Ri2 with 1 outer seta. 



Female.— Length 1.20-1.50 mm. Similar to S. 

 usitatus except S. oligospinosus Mx2 lobe-5 base 

 without spines, and lateral prosomal spinules less 

 numerous on right side. Left Thl, many distinct 

 spinules; Th2-Th3, ca. 25 spinules; Th4, no spinules. 

 Right Thl, many distinct spinules; Th2 few spinules; 

 Th3-Th4, no spinules. 



Al terminal segments (Fig. 158) of moderate length 

 and width. Apparent deviation: L2s; remainder as 

 Table 4. 



Mxp Bl spine-comb sometimes somewhat reduced 

 on one side; holotype with distinct spine-comb left 

 and right. 



P3 ReS with 5 inner setae, not 4 as shown by Park 

 (1970, fig. 65). 



Male. — Unknown. 



Remarks 



Sars (1920; 1924, 1925) described S. caudatus from 

 one female collected in the western Mediterranean. 

 Rose (1933) and Massuti (1939) cited this single 

 record. This species has not been reported from the 

 Mediterranean since the original record. It is possible 

 that S. caudatus is conspecific with S. brevicaudatus, 

 which has not been reported from the Mediterranean. 

 It is also possible that S. caudatus is conspecific with 

 S. oligospinosus which is common at the type locality 

 of S. caudatus. Sars' (1924, 1925) description does not 

 mention lateral prosomal spinules or Mxp Bl spine- 

 comb, both of which could have been overlooked. The 

 prosome/urosome ratio of S. caudatus is consistent 

 with that of S. oligospinosus but not of S. 

 brevicaudatus. The description is not precise enough 

 to separate S. caudatus from other species; in this 

 study, Sars' specimen is considered S. oligospinosus. 

 The holotype S'. caudatus, in poor condition, is on 

 slide F5038, OSLO. 



Hure and Scotto di Carlo (1971) equated their 

 earlier use of S. abyssalis with Grice's manuscript 

 name for S. neospinosus, S. paraoligospinosus (G. 

 Grice, pers. commun.). 



Grice (1971, fig. 2E, G) did not note the presence of 

 4 posterior surface spines on PI Re3, and P3 Ri3 has 6 

 setae.

Wilson (1942) reported S. caudatus in seven 

 samples from the northeast and central Pacific. 

 Wilson's samples 87 and 132 were examined in the 

 present study and found not to contain any 

 Spinocalanidae. The other samples were not located. 



Furuhashi (1966) reported six female S. caudatus 

 from the northwest Pacific; he also reported S. 

 brevicaudatus (as S. pseudospinipes) from the same 

 area, and perhaps the S. caudatus are S. 

 brevicaudatus.

Description 



Pi Ri with 2 inner setae; P2 Ri2 with 1 outer seta. 



Female.— Length (1.65?-) 1.70-2.20 mm (Figs. 141, 

 142). Prosome in dorsal view ovoid, head slightly trun- 

 cate. In lateral view with moderately gentle forward 

 slope. Th4 and Th5 separate; Th5 lateral corners 

 rounded, not prolonged; Thl-Th4 without lateral 

 spinules. Prosome length about 3 '/a times urosome. 

 Genital segment as wide as long, protruding ventrally 

 one-third depth of rest of urosome; caudal rami length 

 slightly greater than width, symmetrical. Caudal 

 setae incomplete on specimens examined; bases 

 appearing symmetrical.
