!2 ORTMANN 



Camb. (Procambarus) cub. Ortmann, Ann. Carnegie Mus., Ill, 



1905,438. 



Among the material from the Paris Museum, sent to me by- 

 Professor Bouvier, the following specimens were present : 



i. i d (II), 2 9. Cuba; Peters. 



2. 4 d (II), i 9. Cuba; Peters. (Nos. i and 2 apparently 

 from the Berlin Mus.) 



3. 2 d (I), 2 d (II), 4 9. "Amerique"; Morelet. (All 

 badly damaged, but copulatory organs well preserved.) 



4. 1 d (I), type of Saussure's C 1 . consobrinus. (Dry specimen, 

 mounted upon a piece of pith ; badly damaged, and copulatory 

 organs not visible.) 



The following remarks are to be made : 



1. C. consobrinus Saussure l is undoubtedly identical with 

 C. cubensis. Although in the present type-specimen the male 

 organs are not visible, it agrees with C. cubensis in all other 

 respects. It has a very small lateral spine on the carapace. 

 But such a spine is also present in two specimens (d and 9) in 

 our first set, while the third (9) has only a trace of it. In the 

 five specimens of the second set, which are all very young, two 

 males (II) have a small granule in its place ; the others are 

 apparently smooth. Of the eight specimens of the third set, 

 one (a male of the first form) shows a small tubercle, and two 

 females have none. The rest is too poorly preserved. 



2. The male copulatory organs (Fig. 3, a-c) need some dis- 

 cussion. The description given by v. Martens (Arch. f. Naturg., 

 38, 1872, p. 129) is quite correct, disregarding a lapsus calami 

 or misprint, that renders a certain passage unintelligible. V. 

 Martens says (translated) : They consist of two parts " an outer 

 one, which ends in a blunt point, and has the anterior margin 

 near this point considerably swollen ; and an inner one, which 

 extends beyond the former posteriorly, and forms on the inner 

 side a plane, ovate face, -which is adjacent to that of the ap- 

 pendage of the anterior side (' zvelche sich an die des Anhanges 

 der vorderen Seite anlegt '). At its end there are two lobes, 

 one in close apposition to the end of the outer part, the second 

 one shorter, projecting separately forward, and more rounded."
